**The objective of this Python post**, you will see various Python programs that cover the following:

- 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

Now let’s see each one by one:

### 1: 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**

Enter the number of which you have to find power: 5 Enter the power: 2 The output 25

### 2: 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**

Enter the number of which you have to find power: 2 Enter the power: 4 2 to the power of 4 is = 16

### 3: 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**

Enter the number of which you have to find power: 10 Enter the power: 2 10 to the power of 2 is = 100

### 4: 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**

Enter the number of which you have to find power: 4 Enter the power: 3 4 to the power of 3 is = 64
