Basic conditions in Python:
< (one less than the other)
> (one more than the other)
<= (one is less than or equal to the other)
>= (one is greater than or equal to the other)
!= (one is not equal to the other)
== (one is equal to the other)
Examples of using conditions:
print(5 > 4)
True #result
print(‘cat’==’dog’)
False #result
The if statement (if) is used to set conditions (if so, then…), for example:
cat_say = ‘mew’
if cat_say = ‘mew’ of cat_say = ‘myavki’:
….print(‘Dear, cat! Here’s your food!’)
Important: when using if conditions, you need to write double equals and put a colon at the end of the expression to show the end of the condition; before the rest of the code related to the condition, and print is indented with a tab (or 4 spaces).
Inside the string, we can specify both fixed text and part of the text defined by the format function, which will consist of separately specified sections:
print(“This cat has {0} kittens and a {1}”.format(2,”tail”))
Instead of using numbers inside curly braces, you can immediately set the value of the variable in them – a,b,c:
print(‘quantity: ({a}, {b}, {c})’.format(a=5,b=2,c=4))
To assign a string to a variable, enclose the test either in apostrophes ‘…’ or in double quotes “…”:
string=’I am a cat’
string=”I am a cat”
If the string contains an apostrophe (I’m), then the entire string must be enclosed in double quotes, and vice versa. If the string contains both an apostrophe and double quotes, then a backslash \ must be used to escape the characters.
When you have installed Python, the question arises – how to start learning this language? Should I write commands through the console or do I need to install something else on the computer? There are many programming environments and solutions for Python, but for a beginner, it is preferable to choose from two:
To install Python on your computer, simply search Google for download python and follow the first link to www.python.org/downloads
The easiest way is to click on the bright button with the latest version of Python and then follow the installation process.
In addition to Python itself, you will probably need to install additional programs, which we will discuss next. When installing Python, remember that it is an interpretive programming language. If you write the code in notepad, it won’t work. And the code doesn’t need to be compiled like in C++. To run your code, you use either the built-in interpreter – Python 3.6.exe, or you can activate the interpreter in other text editors or programming environments.
To find out which names cannot be given to variables in Python, use the command:
import keyword
keyword.kwlist
For Python 3.6 this words are: Continue reading
When we write any program in any programming language, sooner or later we want the result of our programming to be shown to the user. For this we use the command:
print(…) must be lowercase

In the Python programming language, there are three types objects (or data types – data type):
Find out data type in Python:
type(…)
Example:
type(‘a’) – write a command
str – get the answer
To insert ads into a child theme on an Adsense site: add the following code to function.php:
////////////////////////
///Google AdSense:
//
add_action('wp_head', 'wpse_43672_wp_head');
function wpse_43672_wp_head(){
//Close PHP tags
?>
<script data-ad-client="ca-pub-<publisher-numberic-code>" async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<?php //Open PHP tags
}

Don’t forget to replace the publisher’s numeric code (also removing the angle brackets around it).
p.s.
But in general it is more convenient to insert this code through a wordpress widget 🙂
Sometimes you fork a turnip for every firefighter (they sometimes delete it; we know, they passed ..) and you forget about it. But they write something in it, update it – you need to update yours too. The easiest way to do this is through the web interface:
Comparecompare across forksYou can do it through bash, but I have it on a virtual machine and I’m too lazy to go there, in order to make a turnip update 🙂 There are also softins that do this themselves, but somehow I don’t want to litter the computer with them.
I will be glad to your comments!
I’ll tell you what to do if you are forced to store binaries on github. The problem is that they often do not start when Windows downloads from there with a .zip archive (link like https://github.com/[user]/[repo] /main.zip ). To solve this problem, you need to create a .gitattributes file inside, where you specify that git treats everything inside the turnip as binaries and does not put down BOMs (thanks to Serg Bloim for the tip). I do like this:
.gitattributes* binaryIf you’re just getting started with GitHub and using the web interface or GitHub Desktop, doing something as simple as cloning a specific branch of a repository can be quite a challenge. You can do this with Git Bash:
git clone git://github.com/<user>/<repo>.git cd <repo> git checkout <branch>/<name>
This is not taught in school (note to yourself). To calmly work with a fake turnip locally, without hurting your wounds .. Go to the git folder and look for the “exclude” file there:
\.git\info\exclude
we write paths there, for example:
../../xxx/
../../yyy.sh
Sooner or later in the life of every mmm … Malthusian, let’s say .. there comes a moment when you need to learn how to work with the Git like a human being. In particular, engage in gardening – grow branches, graft them, cut them, and so on.
Well, I’m an amateur gardener and always pushed everything into a master. I drove a tank to the store for bread, so to speak.
But the time has come when it is important that the shoots grow in the right direction … Let’s say we made a fork (on the github website, click the button on the top right) and ..
I have been using the wonderful WinMerge tool for a long time, and I wish you the same. And now it’s time to merge conflicts on the git .. and the built-in tools or any alternative Git GUI turned out to be very buggy (tested a dozen) for exactly what I need. As a result, it turned out to be cheap and cheerful to check everything in WinMerge.
To use it, in a file C:\Users\<user>\.gitconfig add:
Found out that git pull stopped working today. Gives an error message:
The unauthenticated git protocol on port 9418 is no longer supported
Solution
First, let’s check where our git is knocking:
git remote -v
If you see the error indicated in the title of this post, then it is knocking on an outdated protocol git://
Now you need to switch to ssh://, https://, or git@github.com. So we write something like:
git remote set-url origin https://github.com/igroglaz/Tangaria.git
Well, only naturally instead of igroglaz and Tangaria – we indicate your turnip 🙂 That’s it, now everything should work. If it doesn’t work, check
