Python program to find power of a number; In this tutorial, you will learn how to find power of a number in python using for loop, while loop, recursion function, and exponentiation.

## Python Program to Find Power of Number

- 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
