Python chr() Syntax


As you can see above, the chr() function takes a single parameter and returns the corresponding character of the integer ASCII value.

For example, chr(97) will return the character a as the ASCII value of a is 97.

The valid range of the integer i is from 0 to 1,114,111 (0x10FFFF in base 16). ValueError is raised when i is out of this range.

Python chr() Example

>>> print(chr(98))
>>> print(chr(555))
>>> print(chr(2000))
>>> print(chr(-2))
Traceback (most recent call last):
ValueError: chr() arg not in range(0x110000)

As you can see in above example, Python interpreter throws a ValuError when an integer out of range is supplied to the function chr().
