how to convert python input to int

1# To prompt the user to input an integer we do the following:
2valid = False
3
4while not valid: #loop until the user enters a valid int
5    try:
6        x = int(input('Enter an integer: '))
7        valid = True #if this point is reached, x is a valid int
8    except ValueError:
9        print('Please only input digits')

1# Any input taken by python is always taken as a string.
2# To convert it to an integer, we have to wrap input() in int(). Example:
3
4num1 = int(input("Enter a number: "))
5num2 = int(input("Enter another number: "))
6total = num1 + num2
7print(f'Sum: {total}')
