In this article, I would like to show an example of how you can make a link on the site so that the user can switch between languages on the site.

But I will show a more advanced version of this functionality, namely saving the selected language in the user table, as well as redirecting the user to a page with the correct language that was selected by the user, if they are of course authorized. That is, if the user has set the German language for himself, then when going to the site via an English link, the site will automatically redirect the user to the page with the German language.

To do this, we need to add a language code field to the user model, I hope that everyone is already using their user model in Django instead of the default one.
Rewrite the standard Django language setup function, and also add a Middleware that will process the urls requested from the site.

Among other things, this functionality will be useful in order to generate letters with the correct language for registered users.

This article is based on Django 4 and may not be suitable for older versions of Django.

For a long time I wanted to write an article on how to write auto populate field functionality for a Django project. This is a very useful feature that allows you to change the content of other model fields in Django by setting a value to a field that uses auto populate.

First, why is it needed? - Such functionality allows you to reduce the size of the code in those places where you need to rewrite other fields of the object when they change. That is, for example, you do not have to redefine the save method each time in order to rewrite some field in case other fields of the object change. Also, using auto populate is basically a more advanced and neat way to manage data models in Django.
And also a similar approach can solve some problems and improve the site.

Remove specific characters from the string

Let's use ' str.replace '

With the help of * str.replace *, we can change some characters to others. If we just want to remove some characters, then we simply replace them with an empty string. * str.replace () * will apply the replacement to all matches found.

s="Hello$ Python3$"
s1=s.replace("$", "")
print (s1)
# Результат: Hello Python3

If we can specify a limit for the number of matches, so as not to remove all characters.

s="Hello$ Python3$"
s1=s.replace("$", "", 1)
print (s1)
# Результат: Hello Python3$

With ' re.sub '

re. sub (pattern, repl, string, count=0, flags=0)

> Returns the string obtained by replacing the leftmost non-overlapping
> matches a pattern in a string to the value repl. If pattern matches
> not found, an unmodified string is returned
> - From Python documentation

If we want to remove characters, then we simply replace the matches with an empty string.

s="Hello$@& Python3$"
import re
s1=re.sub("[$|@|&]","",s)
print (s1)
# Результат: Hello Python3

s1=re.sub(“[$|@|&]”,””,s)

• Template to replace → * “[$ | @ | &] ”*
• • [] * is used to define a set
• • $ | @ | & * → will search for $ or @ or &
• Replace with an empty string
• If the above characters are replaced found, then they are replaced with an empty string

Introduction

One of the most common uses of TensorFlow and Keras is in image recognition and classification. If you would like to learn how to use Keras for image classification or recognition, this article will teach you how to do it.

Definitions

If you do not understand the basic concepts of image recognition, it will be difficult for you to fully understand the main part of this article. Therefore, before we continue, let's define the terminology.
