[Tutor] Type Conversion

[Jessica Brink]

I am doing a simple program that takes input from the user (a temp. in degrees Celsius) and converts it to a temperature in Fahrenheit.  The following program works:
 
def conversion ():
    C = input ("Enter the temperature in degrees Celcius:\n")
    F = (9.0 / 5.0) * C + 32
    print F
 
conversion ()

However, if I try to use the raw_input function, and then convert the variable to an integer, it does not work:
 
def conversion ():
    C = raw_input ("Enter the temperature in degrees Celcius:\n")
    int (C)
    F = (9.0 / 5.0) * C + 32
    print F
 
conversion ()

Am I missing a step on converting the variable C from a string to an integer, or is it not possible to do this?  I get the error that it is not possible to concatenate a str and int.
 
Thanks!
