convert string to int?

Working on a letter-guessing game.

Why is it that in the following example, when I hardcode the value of the variable, "userGuessPosition" to 2, the code works as expected. 

secretWord = ('music')
userGuessPosition = 2 
slice1 = (secretWord.__len__()) - userGuessPosition - 1  
print (secretWord[slice1:userGuessPosition])

But when I rely on the input() function and type in 2 at the prompt, nothing happens?

secretWord = ('music')
userGuessPosition = 0
userGuessPosition == input()
slice1 = (secretWord.__len__()) - userGuessPosition - 1  
print (secretWord[slice1:userGuessPosition])

I assume this is because my keyboard input of "2" is being seen as a string and not an integer. If this is the case, then I'm unclear on the proper syntax to convert it.

The problem is not that the input is recognized as a string, but rather in the syntax: you're doing a comparison operation where you should be doing an assignment operation.

You have to use

userGuessPosition = input()

instead of

userGuessPosition == input()

The input() function actually does convert the input number into the most appropriate type, sp that should not be an issue. If however you need to convert a string (say, my_string) to an integer, all you need to do is my_int = int(my_string).

EDIT

As mentioned below by @HenryKeiter, depending on your Python version, you may in fact need to convert the return value of input() to an integer by hand, since raw_input() (which always takes in the input as a string) was renamed to input() in Python 3.

userGuessPosition = int(input())

(Single =; int converts a string to an int)
