operator.ipow

in-place

In-place exponentiation: a **= b.

Syntax

operator.ipow(a, b)

For ints the result is exact and may be huge: ipow(2, 100) is a 31-digit number with no overflow. A negative exponent on an int yields a float: ipow(2, -1) is 0.5. There is no modular exponentiation like the three-argument pow(base, exp, mod) — use pow for cryptography and large powers modulo n.

Examples

import operator
print(operator.ipow(2, 3))   # → 8
print(operator.ipow(2, -1))   # → 0.5
print(operator.ipow(9, 0.5))   # → 3.0
base = 3   # ни один встроенный тип не меняется по **= — присваивайте результат
print(operator.ipow(base, 4), base)   # → 81 3
print(operator.ipow(2, 10, 1000))   # → TypeError
