本文实例讲述了Python中pow()和math.pow()函数用法。分享给大家供大家参考,具体如下:
1. 内置函数pow()
>>> help(pow)Help on built-in function pow in module __builtin__:pow(...) pow(x, y[, z]) -> number With two arguments, equivalent to x**y. With three arguments, equivalent to (x**y) % z, but may be more efficient (e.g. for longs).>>>>>> pow(3,2) # 3**29>>> pow(3,2,4)# (3**2)%41
2. math.pow()
>>> import math>>> help(math.pow)Help on built-in function pow in module math:pow(...) pow(x, y) Return x**y (x to the power of y).>>> math.pow(3,2)9.0>>>
希望本文所述对大家Python程序设计有所帮助。
