Equivalent to eval(raw_input(prompt)). Warning: This function is not
safe from user errors! It expects a valid Python expression as input;
if the input is not syntactically valid, a SyntaxError will be raised.
Other exceptions may be raised if there is an error during evaluation.
(On the other hand, sometimes this is exactly what you need when
writing a quick script for expert use.)
If the readline module was loaded, then input() will use it to provide
elaborate line editing and history features.

Consider using the raw_input() function for general input from users.

So you want be using raw_input() for starters...
