chr() — Advanced Examples

Returns the character for a given Unicode code point

chr() protocol implementation

Implementing the protocol that chr() uses under the hood.

python

# chr() - implementing the protocol
class Custom:
    def __chr__(self):
        return "custom result"

obj = Custom()
print(chr(obj))

Understanding the dunder methods that chr() calls helps you customize behavior for your own classes.

Handling unusual inputs and edge cases.

python

# chr() edge cases
print("Edge case handling for chr()")

# Type checking
print(type(42))

Knowing these edge cases prevents subtle bugs in production.
