Python chr() Function: Usage and Examples

A log stores character identifiers as integers and must display their symbols.

What You Need to Understand

The built-in chr(number) returns the Unicode character with a given valid code point. It is the reverse operation of ord() for valid values.

When to Use It

A log stores character identifiers as integers and must display their symbols.

Step-by-Step Python Example

print(chr(65))
print(chr(8364))
print(chr(0x1F600))

How the Example Works

The values produce A, €, and a grinning face. Hexadecimal integers are still ordinary integers.

Example Output

A
€
😀
Py3

A Second Example

Compare this smaller variation with the main example, then experiment with your own values.

codes = [80, 121, 51]
print("".join(chr(code) for code in codes))

Important Behavior and Edge Cases

Values outside the valid Unicode range raise ValueError. Printing a character also depends on terminal font support.

Try It Yourself

Convert the integers 72, 105, and 33 into a short greeting.

Common Beginner Mistakes

• Values outside the valid Unicode range raise ValueError. Printing a character also depends on terminal font support.
• Applying a string method before defining whether text is intended for display, comparison, parsing, or input validation.

Key Takeaways

• The built-in chr(number) returns the Unicode character with a given valid code point.
• The values produce A, €, and a grinning face.
• Values outside the valid Unicode range raise ValueError.
