Python program to find or calculate power of number; Through this tutorial, i am going to show you how to find or calculate power of number in python.
Python Program to Find or Calculate Power of Number
Let’s see the following programs to find or calculate power of number; as shown below:
- Python program to find power of a number using for loop
- Python program to find power of a number using while loop
- Python program to find power of a number using recursion
- Python program for exponentiation of a number
Python program to find power of a number using for loop
num = int(input("Enter the number of which you have to find power: ")) pw = int(input("Enter the power: ")) CP = 1 for n in range(pw): CP = CP*num print("The output " , CP)
Output of the above program; as shown below:
Enter the number of which you have to find power: 5 Enter the power: 2 The output 25
Python program to find power of a number using while loop
num = int(input("Enter the number of which you have to find power: ")) pw = int(input("Enter the power: ")) # calculating power using exponential oprator (**) power = 1 i = 1 while(i <= pw): power = power * num i = i + 1 print (num, " to the power of ", pw, " is = ", power)
Output of the above program; as shown below:
Enter the number of which you have to find power: 2 Enter the power: 4 2 to the power of 4 is = 16
Python program to find power of a number using recursion
def powerRecursive(num,pw):#function declaration if(pw==1): return(num) if(pw!=1): return (num*power(num,pw-1)) num = int(input("Enter the number of which you have to find power: ")) pw = int(input("Enter the power: ")) # calculating power using exponential oprator (**) result = powerRecursive(num,pw) print (num, " to the power of ", pw, " is = ", result)
Output of the above program; as shown below:
Enter the number of which you have to find power: 10 Enter the power: 2 10 to the power of 2 is = 100
Python program for exponentiation of a number
num = int(input("Enter the number of which you have to find power: ")) pw = int(input("Enter the power: ")) # calculating power using exponential oprator (**) result = num**pw print (num, " to the power of ", pw, " is = ", result)
Output of the above program; as shown below:
Enter the number of which you have to find power: 4 Enter the power: 3 4 to the power of 3 is = 64
