ord() and chr() Function in Python.

In Python, the ord() and chr() functions are essential tools for working with Unicode, they allow you to convert an integer to Unicode and Unicode to an integer respectively. Let's dive deeper into these functions.

What is Unicode?

Unicode is a standardized character encoding system that assigns a unique number, known as a code point, to every character in almost every script and language in the world. It is designed to be a universal character set, encompassing characters from different writing systems. For example, 'A' is assigned the code point 65, and '❤' is assigned the code point 2764.

What is ord() in Python?

The ord() function in Python is a built-in function that returns an integer representing the Unicode character. It stands for "ordinal," and its primary use is to obtain the Unicode code point of a given character.

Syntax:

ord(character)

# Using ord() to get the Unicode code point of a character

unicode_value = ord('A')

print(f"The Unicode code point of 'A' is {unicode_value}")

The Unicode code point of 'A' is 65

What is chr() in Python?

# i is an integer representing an integer point
chr(i)

# Using chr() to convert a Unicode code point to a character
unicode_code_point = 65  # Unicode code point for 'A'
character = chr(unicode_code_point)

# Printing the result
print(f"The character to the Unicode code point {unicode_code_point} is: {character}")
