Python 程序：计算数的幂

写一个 Python 程序，用一个例子求出循环数、While 循环数和幂函数的幂。

这个 Python 程序允许用户输入任何数值，指数。接下来，这个 Python 程序使用求循环来求一个数的幂。

# Python Program to find Power of a Number

number = int(input(" Please Enter any Positive Integer : "))
exponent = int(input(" Please Enter Exponent Value : "))
power = 1

for i in range(1, exponent + 1):
    power = power * number

print("The Result of {0} Power {1} = {2}".format(number, exponent, power))

Python 数字幂用于循环输出

 Please Enter any Positive Integer : 3
 Please Enter Exponent Value : 4
The Result of 3 Power 4 = 81

这个数字程序的幂和上面一样，但是这次我们用的是 While Loop

# Python Program to find Power of a Number

number = int(input(" Please Enter any Positive Integer : "))
exponent = int(input(" Please Enter Exponent Value : "))

power = 1
i = 1

while(i <= exponent):
    power = power * number
    i = i + 1

print("The Result of {0} Power {1} = {2}".format(number, exponent, power))

使用 while 循环输出 时的 Python 幂

 Please Enter any Positive Integer : 10
 Please Enter Exponent Value : 5
The Result of 10 Power 5 = 100000

这个 Python 程序示例接受来自用户的数字和指数。接下来，我们使用内置的数学函数调用幂来求一个数的幂。

# Python Program to find Power of a Number

import math

number = int(input(" Please Enter any Positive Integer : "))
exponent = int(input(" Please Enter Exponent Value : "))

power = math.pow(number, exponent)

print("The Result of {0} Power {1} = {2}".format(number, exponent, power))
