input() command not working on Sublime Text 3 [duplicate]

Question

I'm trying to write an add() function using input(), however it seem that the input doesn't really work for me. The module is as following:

def add (n1, n2):

    return (n1+n2)

def main ():

    print (add(input("Enter number one, please:"),input ("Enter number two, please:")))

if __name__ == "__main__":
    main()

When ran, I just get the "Enter number one, please:" prompt, and when inputting an actual number and pressing ENTER, nothing really happens. I tried getting the "Sublime Input" package, but to no avail.

I'd like to get this to run without resorting to Ubuntu (I'm using Windows 8.1).

Answer 1

First off input in Python 3 no longer interprets the data type you are giving to it. This in essence means that everything you give it will be read as a string. This mean the add function will not work as you are expecting it to. To fix this change the code to the following:

def add (n1, n2):

    return (n1+n2)

def main ():

    print (add(float(input("Enter number one, please:")),float(input ("Enter number two, please:"))))

if __name__ == "__main__":
    main()

The addition of the builtin float function ensures that the input in converted into a float and you can therefore to math operations on it.

Secondly, Sublime Text 3 is still in its beta development stage. This means that some features might not work as you would expect. Try using Sublime Text 2. Also I ran the above code in the command line using python add.py and it works perfectly. NOTE: I saved the file as add.py
