So let’s start by asking ourselves: what exactly are Unicode literals in Python? Well, they’re just fancy ways to write text that includes characters from all over the world. You know, like those ***** accents and symbols you can’t find on your keyboard. Don’t Worry! With Python, we have six different ways to type these magical creatures.
First up is the most common method: typing them literally. For example, if you want to write “Python” in Spanish (which sounds like a paradox), you would use this code:
# This script prints the word "Pytón" using the print() function
# The print() function takes in a string as an argument and displays it on the screen
print("Python") # The string "Python" is misspelled as "Pytón" and needs to be corrected
Voilà! You’ve just written Python in Spanish using Unicode literals. But what about those ***** accents? Well, that’s where things get interesting (or boring, depending on your perspective). Let’s say you want to write “Python” with an accent over the ‘o’. Here’s how:
# This script prints the word "Python" in Spanish using Unicode literals and demonstrates different ways to add accents to the word.
# The first line prints "Pytón" using a regular string.
print("Pytón")
# The second line prints "Pýton" by adding a backslash before the 'y' to indicate that it is a literal backslash, not a newline character.
print("Pýton")
# The third line prints "Py\u0308n" by using a raw string (starting with 'r') and adding the Unicode code for the accent over 'o'.
print(r"Py\u0308n")
Now you might be wondering: why would anyone use all these different methods to write text? Well, it’s because Python is a Unicode-centric language. This means that every character in your program has an associated number (called its “code point”) which can be used to represent the character in any programming language or operating system.
So if you want to make sure that your code works on all platforms, it’s best to use Unicode literals instead of relying on specific fonts and encodings. Plus, it just looks cooler!
