带有Python示例的math.pow()方法
Pythonmath.pow()方法
math.pow()方法是数学模块的库方法，用于计算基数的给定幂，它接受两个数字并将第一个数字返回浮点数中第二个数字的幂。
它的语法math.pow()方法：
math.pow(a, b)
Parameter(s)：a，b–需要计算其幂的数字（此处，a是基数，b是将结果a乘以b的幂的幂）。
返回值：float-它返回一个浮点值，即a乘以b的幂。
示例
Input:
a = 2
b = 3
#函数调用
print(math.pow(a, b))
Output:

输出结果
2 to the power of 3 is = 8.0 2.2 to the power of 3.0 is = 10.648000000000003 2 to the power of 0 is = 1.0 0 to the power of 3 is = 0.0
