# Python3.x Python chr() Function
[ Python3 Built-in Functions](#)
* * *
`chr()` is a built-in function in Python used to convert an integer to its corresponding character.
`chr()` takes a Unicode code point (an integer) and returns the corresponding character. It is the inverse function of `ord()`.
**Word Origin**: `chr` is an abbreviation for `character`.

## Basic Syntax and Parameters
### Syntax Format
chr(i)
### Parameter Description
* **Parameter i**:
* Type: Integer (Unicode code point, 0 to 1,114,111)
* Description: The Unicode code point to convert to a character.
### Function Description
* **Return Value**: Returns a string of length 1, which is the corresponding character.
* **Range**: The valid Unicode code point range is 0 to 1,114,111 (0x10FFFF).

## Examples
### Example 1: Basic Usage
## Example
# Basic English characters
print(chr(65))# Output: A
print(chr(90))# Output: Z
print(chr(97))# Output: a
print(chr(122))# Output: z
# Digit characters
print(chr(48))# Output: 0
print(chr(57))# Output: 9
# Common symbols
print(chr(33))# Output: !
print(chr(64))# Output: @
print(chr(32))# Output: space
# Chinese characters
print(chr(20013))# Output: in
print(chr(25991))# Output: Text
**Expected Output:**
A Z a z 09!@Chinese
**Code Explanation:**
1. 65-90 are the Unicode code points for uppercase letters A-Z.
2. 97-122 are the Unicode code points for lowercase letters a-z.
3. 48-57 are the Unicode code points for digits 0-9.
### Example 2: Used with ord()
## Example
# ord() is the inverse function of chr()
print(ord('A'))# Output: 65
print(chr(65))# Output: A
print(chr(ord('A') + 1))# Output: B
# Iterate through uppercase letters
for i in range(65,91):
print(chr(i), end=" ")
print()# Output: A B C ... Z
# Generate an ASCII art pattern
pattern =[]
for i in range(0,256,16):
row =''.join(chr(j)for j in range(i,min(i+16,256)))
pattern.append(row)
print(pattern)# Output: !"#$%&'()*+,-./
**Expected Output:**
65 A B A B C D E F G H I J K L M N O P Q R S T U V W X Y Z !"#$%&'()*+,-./
`chr()` and `ord()` are inverse functions, often used together to handle character encoding.
