python遞歸查找

Given the base x and the power y and we have to find the x to the power y using recursion in Python.

給定基數(shù)x和冪y ，我們必須使用Python中的遞歸找到x到冪y 。

By using recursion – We will be multiplying a number (initially with value 1) by the number input by the user (of which we have to find the value of y^th power) for y times.?For multiplying it by y times, we need to call our function y times. Since we know the number of times function will execute, so we are using for recursion.?

通過使用遞歸–我們將一個數(shù)字(最初是值1)乘以用戶輸入的數(shù)字(必須找到y(tǒng) ^次方的值) y次。 為了將它乘以y倍，我們需要調(diào)用函數(shù)y倍。 由于我們知道函數(shù)執(zhí)行的次數(shù)，因此我們將其用于遞歸。

Python code to find the power of a number using recursion

Python代碼使用遞歸找到數(shù)字的冪

# Python code to find the power of a number using recursion # defining the function to find the power # function accpets base (x) and the power (y) # and, return x to the power y def pow(x, y):if y == 1:return xelse:return pow(x, y-1) * x# main code if __name__ == '__main__':x = 2 #basey = 3 #powerresult = pow(x, y)print(x," to the power ", y, " is: ", result)x = 10 #basey = 3 #powerresult = pow(x, y)print(x," to the power ", y, " is: ", result)x = 12 #basey = 5 #powerresult = pow(x, y)print(x," to the power ", y, " is: ", result)

Output

2 to the power 3 is: 8 10 to the power 3 is: 1000 12 to the power 5 is: 248832
