In this article, you will learn how to use the Python ord() function.

Python ord() Function

In Python, the ord() function is used to get the integer Unicode code point of a given Unicode character. Here’s how you can use the ord() function in Python:

  1. First, choose the Unicode character for which you want to get the code point. You can use a single character or a string of characters.

  2. Call the ord() function and pass in the character as an argument. For example:

    >>> ord('A')
65

In this example, the ord() function returns the integer value of the Unicode code point for the character “A”, which is 65.

Note that the ord() function only accepts a single character as input. If you pass a string with multiple characters, you will get a TypeError.

>>> ord('hello')
Traceback (most recent call last):
  File "", line 1, in 
TypeError: ord() expected a character, but string of length 5 found

In this example, the ord() function raises a TypeError because it expects a single character but receives a string of length 5.

That’s how you can use the ord() function in Python to get the integer Unicode code point of a given Unicode character.

 

Here are a few more things you should know about the ord() function in Python:

  • The ord() function is a built-in function in Python, which means you don’t need to import any module to use it.
  • The ord() function can be used to get the Unicode code point of any Unicode character, including non-Latin characters.

  • The ord() function can also be used with escape sequences, such as \n, to get the Unicode code point of special characters. For example:

    >>> ord('\n')
10

    In this example, the ord() function returns the integer value of the Unicode code point for the newline character, which is 10.

  • The ord() function can be used in conjunction with the chr() function to convert between Unicode code points and their corresponding characters. For example:

    >>> chr(65)
'A'
>>> ord('A')
65

    In this example, the chr() function takes the integer value of the Unicode code point for the character “A” and returns the corresponding character. The ord() function does the opposite: it takes the character “A” and returns the integer value of its Unicode code point.
