ArithmeticError

built-in exceptions

Base class for arithmetic errors: ZeroDivisionError, OverflowError, FloatingPointError.

Syntax

raise ArithmeticError

Catching the base class is rarely what you want — in practice only ZeroDivisionError ever surfaces here, so name it directly in your except. Its siblings are misleading: ordinary float arithmetic that goes too far yields inf rather than an error (1e308 * 10), OverflowError shows up only in narrow spots such as float exponentiation and math functions, and FloatingPointError is never raised by CPython itself.

Examples

try:
    raise ArithmeticError
except ArithmeticError as e:
    print(type(e).__name__)   # → ArithmeticError
