int_rate =float(input('Enter the annualized interest rate in percentage:'))

Question

what is wrong with this problem:

int_rate=float(input('Enter the annualized interest rate in percenage:')

It want let me run because it gives me an error saying that it cannot convert string into float. I'm confused

Answer 1

Python cannot convert strings directly into integers if there are any non-integer characters in the string. Your prompt about annualized interest rate percentages may make the user input a string such as "3%" which would contain the non-integer character "%."

To remedy this problem, you can try formatting the string before processing it.

input_string = input("Enter the annualized interest rate in percenage:")
int_rate = float(input_string[:-1] if input_string[-1] == "%" else input_string)
