Python Programming Language

There is a lot of great info. however the 3 hole punched is over some text so words are missing. The picture online does not show the 3 hole punch and would be better without. The hole punched at the bottom removed text from ‘Making Variables’.

As an experienced engineer trying to ramp up quickly on python, this is just what I was looking for: a terse, compact overview of the language. If anything, it gives more than I need from a resource like this; I don't need definitions of variable, recursion, polymorphism, etc. What I do need is a quick cheat sheet of things like what data structures exist natively and what the the syntax is for working with them. Or the syntax for declaring a class member variable, or the most idiomatic way of writing a for loop. This six page resource is exactly that.To clarify the format, it is actually three sheets printed front and back, in a trifold arrangement. The holes of the three hole punch are along one of the folds, and the third page is slightly shorter so that it folds in like a magazine centerfold. (It would be incredibly useful for a student who is already carrying around three ring binders of notes and study materials.) It is true that the hole punch could have been planned a little better; a few words were cut out. But I included a photo of the only one of the 12 places (3 holes * 2 sheets * 2 sides of each sheet) affected by the hole punch where the content was actually obscured. It is quite easy to figure out what's missing, and the other 11 places fall where there was no content to obscure, so please don't let that issue hold you back from purchasing this excellent quick reference.

The information is good, however having 3 hole punched ruins it.. The picture online does not show the 3 hole punch.

Good buy for the price and exactly what I was looking for. It does have holes punched in it for use in a binder, but I do not feel like they are an issue and no commands are missing because of it.

Glad i bought this. It is a handy, quick reference for the majority of Python vernacular userful for student to seasoned programmer. You can find all the info on the Web of course, but it's great that you can put it in your 3-ring binder as a ready reference among your books.The 3 -ring binder hole punches obscure a couple pieces of info (the company should probably address that in next releases). but it's no deal- breaker.This reference is well made and worth the money -- especially if your tired of looking at screen all day!

The info on this sheet is a great summary and a very convenient and helpful quick reference. I haven't found any errors, but I'm still learning so something on there might be off, but so far every discussion and command description I've used is accurate. The lamination seems very good. As a matter of fact, the way the pages are placed and the plastic applied, the 'hinge' is very flexible and the whole thing easily folds flat and stays that way. Sometimes a menu in a restaurant won't fold along the crease well, and wants to open up. This will fold flat and stay that way. Very unexpected and very nice.

I was hoping this would be a cheat sheet for when I didn’t remember syntax or function name but this is a condensed pamphlet that is more like an introduction to Python. In prime real estate, first page, upper left the author provides reasons why Python is good. Really? I think it is safe to assume I knew that because I bought the product. In its defense, it says it is a QuickStudy tool, not cheat sheet. Why they would laminate such a thing is a mystery. Save your money and Google “Python language”

Just learning Python for personal / semi-professional reasons...The examples via code snippets are terse - yet clear and concise - for example showing all the list operations....I also got the Python Standard Library reference for when I get to that level of coding... Indispensable! 6 stars!!

Great hot-weather lightweight boot. Very comfortable. The boot is fully lined and the nylon is padded, but probably not waterproof. Fits slightly like a cowboy boot, somewhat narrow, which I like. Some ventilation holes but no grommets, so these are OK for somewhat wet conditions -- you won't soak your feet by stepping in a puddle which lets water in through large grommet holes, like many hot-weather boots. The coyote color looks great. Some have mentioned that heel rub is a problem because the heel is so fitted, but I find that if you lace these properly, not too tight in the wrong places, then there is no heel rub even after hours of hiking. Highly recommended -- you will be happy!UPDATE: I encountered more heel rub in one foot. By experimenting, I discovered that I could eliminate this heel rub by not lacing the boots all the way up. If I leave the top eyelets open, the heel rub stops. Therefore, as I continue to break these in, I see that the heel needs to break in for the heel rub to cease being a problem. So I took off one star. Still, when these boots work well, they are extremely comfortable. I just have to be careful about the heel.

I’ve been wearing combat boots daily for over 20 years. These are the first pair I’ve had that started falling apart at only 6 months. The eyelets for the laces are all crumbling and the suede is very poor quality. It’s shredding in the Achilles. Usually I get over a year out of boots while in garrison. Also the lack of a heel or support took Some getting used to. I won’t buy from bates again. There’s a reason the Army issues bates... they’re Cheap. Get something of better quality if you wear combat boots professionally.

Unfortunately, I have to agree with other reviewers of these boots. I have been wearing my newest pair for less than a month in a garrison environment (not in the field at all). One of the eyelets has already popped out and the hole where the lace pulls through is now at risk of being torn when the boot is laced up everyday. When it does tear, these boots will be un-serviceable.I had ordered this exact pair of boots about a year or two ago and it is still holding up except for normal wear on the rear sole. That pair has been the best pair of boots I have owned.Bates, please fix your quality control issue on the eyelets. This small defect can easily lead to the boots lasting only a few months.

I've only had the boots for a few months now, so I haven't had time to really test their long-term durability, but I can speak some to the comfort and construction.One thing I was looking for in my new boots was light weight without a significant compromise in durability, and these seem to fit the bill. They're pretty light and flexible (compared to the relatively stiff sole of the standard-issue Army boots) and I can run in them without the weight being much of a bother. The boots were pretty comfortable for me almost right out of the box, and I didn't feel like they required much break-in time. They were rubbing my heel a little, on a hike, but not too bad.After my last hike, I did notice a small piece of the sole ripped off. It was one of the "knobs" that protrude out from the boot in the back. However, I am pretty rough on boots and usually hike in very rocky areas. Also, the hex pattern soles seem to grip terrain pretty well.One thing I would note on the construction: I noticed that the stitching was starting to come loose in a few spots, very soon after getting the boots. It was nothing major, just a few little threads working their way out. However, my standard procedure with all my boots is to put super glue on the stitching in certain places to protect it and prevent it from coming apart.So far, the only two complaints I have are as follows:One, the lack of a pull loop in the back to make pulling the boot on easier. In my opinion, that should be a standard feature on boots, and I will probably have some sewn on in the future.Two, is the lacing system. One thing I appreciate about the standard-issue army boots is the design of the eyelets, which allow you to pull all the laces tight quickly and easily because there's very little friction. These Cobra boots are not as quick to lace up. I have to pull the laces tight one pair of eyelets at a time, working my way to the top of the boot. It may not be a huge deal to some people, but sometimes it pays to save a few seconds getting your boots on.Perhaps I will update my review in the future when I've put more miles on them and had a chance to test their performance in a wet environment.

A friend of mine got these a couple months ago and said they were very comfortable. I tried her pair on to test the fit for myself and immediately ordered a pair. These boots look great and fit comfortably. There has been no need to break them in. It's like walking on pillows but with good support.Edit: I've bought two pairs of these in the last year and a half. I have an issue where the eyelets keep busting off. While the leather has not torn where the laces pull, it doesn't look good or professional. The fabric on the inside of the heel has also been torn up considerably. The soles of the second pair started falling apart a few months into wearing them. I did not bring either pair home from my deployment. While still rather comfortable overall, I will not be buying these boots again.I will however note that my above mentioned friend's boots have not deteriorated like mine have. I do not know if I am that much rougher on my boots or if she just has better luck.

Comfortable and light. You might get 6 months to a year out of them which is typical for any "sneaker" boot I've worn. Worn almost everyday in the summer and half as much in the fall in very rocky areas of eastern Oregon. They are definitely breaking down after six months, having to shoe-goo some of the seams and toes where the boot and sole meet. I'd expect they will remain serviceable into spring when the soles will be mostly slicked off. If you want something lasting a number of years buy a good leather (sewn not glued) boot and ones that the soles can be replaced. I still like this boot because they are so comfortable and I'll likely buy another pair.

So far I discovered 2 code errors for their recursion function addchain sample code on page 5 of their so called cheat sheet. I'm to try all their code provided to see if it's error free. I found another code error but this one is for statement on page 3 for 1st example listed

Add this to your python tool kit you will need it . I use it a lot.

This is a quick reference for all things python. Great resource!

This was a great help with my Python class.It covers the topics for programming language.

This came in handy as I was reading the book and practicing writing code.

It is easy to read and reference.

These are awsome. I'm a millwright and I beat the living hell out of them, and I don't mean that I use them to tighten the seat on my son's bike once a year like most of the other reviews. I mean it more like I beat them with a hammer and put a 12" cheater on the 3/8 and stand on it. They're like a old Hyster they love neglect and abuse. Great product at a good price. the little flip out mechanism on the holder broke after a month but stuff happens when you party hard.

Great set of hex keys. I use these professionally all day long in my Job as a forklift mechanic. I haven’t found a longer set of hex keys. So far they have held up to 5 months of professional use. No wear on the tips. Often, I put a combination wrench on one end to break free stuck/over torqued fasteners with no ill effect. My two complaints are that they are expensive, and the flip mechanism has broken on one set. Honestly, the broken flip mechanism doesn’t effect use and should just be done away with. If you break these you are point blank using them wrong. If you need a set of hex keys and can’t lug around a set of socket hex keys then these are the ones you want.

Since trying Wiha after messing around with ikea type of cheap hex keys all the way up to Snap on brand hex keys, I now only buy and trust my wiha sets. They far out preform all the rest. Very seldom during my extensive and often abusive use of their tools have I ever snapped one. Still have not really bent a key either, nor have I stripped one out. These are an everyday carry tool for me, they get pulled out at nearly every job I take.Occasionally, out of a new pack of keys, I'll have to skate a file across the ends of a couple keys to get them to properly seat into fasteners, not sure if it is the fault of Wiha or the fault of worn out fastener manufacturing tooling. Either way, it is an easy one time fix and well worth it. I wholly (and only) recommend Wiha hex keys to coworkers and anyone looking for a high quality set of hex keys.

Quality high end tools. Last allen wrenches im likely to ever buy, As long as theyre not stolen or lost.Only bad thing: the design of the case can lead to bent wrenches. The little slim ones aren’t shielded by the big fatties.... pack into your box/bag with care.Sent bent set in for an exchange.Still, pack with care. They are fantastic!

Saw these on project farm and needed some for work. Finally got to use them today and they lock in and don't move, tight fit. These won't disappoint or let you down when a money making machine is waiting for you to fix it.

These are the hardest Allen wrenches I have owned. I have had other brands either round out the socket or the wrench corners. Hasn't happened with these. An unexpected (to me, anyway) bonus is the holder. When one wrench is rotated outward, they all rotate out. Makes it easier to select the one you need and readily remove it. If these wrenches went missing tomorrow, I'd buy them again tomorrow night.

I've used three sets of these in nine years with daily use and only because I lose the most important ones for my job as a maintenance mechanic. Not because they've rounded out or anything but because people borrow them lose them. I also bought them because they resist rust a lot better than the regular black steel Allen keys.

I use hex keys almost every day and for a long time I had a set of Craftsman brand wrenches. Through the years I've lost a few and had some round off that were commonly used. With these, I don't know that I'll have to worry about that! The convenient storage assembly makes it perfect for my tool bag (Klein 5541610-14) and keeps me accountable for missing keys. I've used these on numerous tasks, some of the most difficult included removing a motor coupling that was so rusted I had to wire brush the cap screws to even get the Allen in and even pulling on the end with all my might to get them busted free not a single permanent deflection of sign of failure. Highly recommended for someone looking for quality tools!

It is easy to read and reference.

Super helpful and effective format &tips!

This Quick Study card is an excellent reference for Python. I've bought 4 of them for work, for home, for lab, for spare!

This is a nice python programming reference to have handy. Sometimes I’ll just pick it to randomly review some python topic.

I was concerned with the hole punch reviews, and maybe they’ve seen them but the holes on mine do not remove any words.
