chr() — Expert Examples
Returns the character for a given Unicode code point
chr() performance and internals
Performance characteristics and CPython implementation details.
python
# chr() internals import dis def using_chr(): return chr(42) # Bytecode analysis dis.dis(using_chr) # Check if it's truly built-in import builtins print(f"\nchr is builtin: {hasattr(builtins, 'chr')}") print(f"Type: {type(builtins.chr)}")
Understanding the internal implementation helps optimize hot paths in performance-critical code.
