Python 程序：計算數的冪

寫一個 Python 程序，用一個例子求出循環數、While 循環數和冪函數的冪。

這個 Python 程序允許用戶輸入任何數值，指數。接下來，這個 Python 程序使用求循環來求一個數的冪。

# 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 數字冪用於循環輸出

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

這個數字程序的冪和上面一樣，但是這次我們用的是 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 循環輸出 時的 Python 冪

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

這個 Python 程序示例接受來自用戶的數字和指數。接下來，我們使用內置的數學函數調用冪來求一個數的冪。

# 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))
