What are ord() and chr() functions in Python?

ord() function

The ord() function is a built-in function in Python that converts a specified character into an integer

Syntax:

ord(a)

Example: A string of length 1 returns an integer representing the Unicode code point of the character when an argument is a Unicode object or the byte’s value when the argument is an 8-bit string. So, if we take ord(‘a’) it returns the integer 97, and ord(‘€’) (Euro sign) returns 8364.

Note: If the length of a string is more than one, a TypeError will be raised.

print(ord('A'))
print(ord('a'))
print(ord('&'))

chr() function

The chr() function is a built-in Python function that converts a specified integer value into a character.

Syntax:

String chr(n)

The valid range for n is 0 to 1,114,111.

The chr() function returns a string that represents a character whose Unicode code point value is n.

Note: If an integer is passed outside the range, the method returns a ValueError.

Example

print(chr(65))
print(chr(36))
print(chr(97))
