Python chr()

The chr() method returns a character (a string) from an integer (represents unicode code point of the character).

The syntax of chr() is:

chr(i)

1. chr() Parameters

chr() method takes a single parameter, an integer i.

The valid range of the integer is from 0 through 1,114,111.

chr() returns:

• a character (a string) whose Unicode code point is the integer i

a
A
Ұ

Here, 97 is the unicode of a, 65 is the unicode of A, and 1200 is the unicode of Ұ.
