chr() Builtin Function
Python - chr()
Python chr() builtin function is used to convert a given Unicode code point to a character.
In this tutorial, you will learn the syntax of chr() function, and then its usage with the help of example programs.
Syntax
The syntax of chr() function is
chr(x)where
| Parameter | Description |
|---|---|
x | An integer value representing a Unicode code point |
x must be in the range(0x110000).
Examples
1. Convert Unicode code point to character
In the following program, we pass a value of 65 to the chr() function. Unicode code point 65 represents the character: capital alphabet A.
Python Program
x = 65
output = chr(x)
print(f'x : {x}')
print(f'chr(x) : {output}')Output
x : 65
chr(x) : A2. chr() with invalid Unicode code point as argument
A valid Unicode code point is in the range(0x110000). If we give a number out of this range as argument to chr(), it raises ValueError as shown in the following.
Python Program
x = 12685000
output = chr(x)
print(f'x : {x}')
print(f'chr(x) : {output}')Output
File "/Users/pe/Documents/workspace/python/example.py", line 2, in <module>
output = chr(x)
ValueError: chr() arg not in range(0x110000)Summary
In this tutorial of Python Examples, we learned the syntax of chr() function, and how to get the character for a given Unicode code point, with examples.
