Today we’re going to talk about something that might seem like a minor detail at first glance, but can actually have some pretty significant implications for your code. I’m talking, of course, about Unicode identifier syntax in Python.

Now, if you’ve been programming with Python for any amount of time, you probably already know that identifiers (i.e., variable and function names) are typically made up of letters, numbers, and underscores. But what happens when we want to use non-ASCII characters in our identifiers? Well, my friends, that’s where things get interesting!

In Python 3.0 and beyond, you can now use Unicode characters in your identifier names. This might seem like a small thing at first, but it opens up all sorts of possibilities for working with non-Latin scripts or special characters. For example:

# This script is used to write the string "test" into a file named "records.log" in the temporary directory "/tmp".
# The "with" statement ensures that the file is automatically closed after the code block is executed.

# The variable "répertoire" is assigned the string value "/tmp/records.log".
# The "r" before the string indicates that it is a raw string, which is used to avoid any special characters being interpreted.

# The "open()" function is used to open the file in write mode, indicated by the "w" parameter.
# The "as" keyword is used to assign the file object to the variable "f".

répertoire = "/tmp/records.log"
with open(répertoire, "w") as f:
    # The "write()" method is used to write the string "test" into the file.
    f.write("test\n") # The "\n" is used to add a new line after the string is written.

Pretty cool, right? You can also use emojis in your identifiers if you really want to (although I don’t recommend it). Here’s an example:

# This script creates a variable named "_burger" and assigns it the value "yum!"
_burger = "yum!"

# This line prints the value of the variable "_burger"
print(_burger)

Now, before we get too carried away with our newfound Unicode identifier powers, let me just say that there are a few things to keep in mind. First of all, not all operating systems and text editors support Unicode identifiers out of the box. So if you’re working on a Windows machine or using an older version of your favorite IDE, you might run into some issues.

Secondly, while it can be tempting to use emojis in your code for fun (or maybe even as a way to communicate with other developers who are also fluent in emoji), it’s generally not recommended. Emojis can make your code harder to read and understand, especially if you’re working on a team or collaborating remotely.

Finally, let me just say that while Unicode identifiers might seem like a small thing at first glance, they actually have some pretty significant implications for the future of Python programming. As more and more people around the world start using non-Latin scripts in their daily lives (whether it’s Mandarin or Arabic), we need to make sure that our software can handle those characters with ease. And by embracing Unicode identifiers, we’re taking an important step towards making Python a truly global language.
