The chr() function in Python is a built-in function that returns a string representing a character whose Unicode code point is the integer parameter. It takes an integer (decimal or hexadecimal) as input and returns a string of length 1 that contains the corresponding Unicode character.
Syntax
chr(i)
i – the integer representing the Unicode code point of the character to be returned.
Return value
The chr() function returns a string of length 1 containing the Unicode character corresponding to the input integer code point.
Examples
Example 1: Return the character for a decimal code point
print(chr(97))
Output: 'a'
Example 2: Return the character for a hexadecimal code point
print(chr(0x41))
Output: 'A'
Example 3: Return the character for a code point outside the ASCII range
print(chr(0x1F600))
Output: '?'
Use Cases
The chr() function is commonly used in Python for the following purposes:
- Converting code points to characters in Unicode
- Generating strings containing special characters
- Decoding and encoding text in different character sets
In conclusion, the chr() function is a useful tool for working with Unicode characters in Python. It takes an integer representing a Unicode code point and returns the corresponding character as a string of length 1. This function can be used for various purposes, including generating strings with special characters, decoding and encoding text, and more.
