Can't print out function result in Python

Question

I'm new to Python and after going through an example using a function to raise a number to a specific exponent, I tried to have it as the user for the numbers instead of just inputting them into the code.

Below is what I have:

def raise_to_power(base_num, pow_num):
    int(base_num)
    int(pow_num)
    result = 1
    for index in range(pow_num):
        result = result * base_num2

    return result


base_num = input("What number would you 
like to exponentially raise?: ")

pow_num = input("To what power?: ")

print(raise_to_power(base_num, pow_num))`

When I try to run it though, I get the error listed below:

Traceback (most recent call last):
File "C:/Users/PycharmProjects/Exponent 
Function.py", line 17, in <module>
print(raise_to_power(base_num, pow_num))
File "C:/Users/PycharmProjects/Exponent 
Function.py", line 7, in raise_to_power
for index in range(pow_num):
TypeError: 'str' object cannot be 
interpreted as an integer

Could someone explain why this might be happening?

Thank you,

int(base_num) doesn't change the argument. To convert the base_num to string and save into the same variable use:

base_num = int(base_num)

This code sample shows some weaknesses of the design: why should base_num be of the string type initially. Try to call the variables with more meaningful names that would avoid this confusion.

your conversion of input string to integer is not correct.

Try the below code:

def raise_to_power(base_num, pow_num):  
    result = 1
    for index in range(int(pow_num)):
        result = result * int(base_num)
    return result

You did two mistake. 1- int(base_num) is not good way to type casting. 2- In method you are passing base_num but in for loop you are using base_num2. Here is the correct code.

def raise_to_power(base_num, pow_num):
    result=1
    for index in range(int(pow_num)):
        result = result * int(base_num)
    return result
base_num = input("What number would you")
pow_num = input("To what power?: ")
print(raise_to_power(base_num, pow_num))

def raise_to_power(base_num, power_num):

    result = 1

    for index in range(power_num):
        result = result * base_num

    return result 
          
base_num = input("enter a base number you want : ")
power_num = input("enter the power of base number : ")

print(str(raise_to_power(int(base_num), int(power_num))))
