#26394 — consistent input() for Python 2 and 3

Hi!

I'm trying to write some code that should work with both Python 2 and 3. 
One of the problems there is that the input() function has different 
meanings, I just need the raw_input() behaviour of Python 2.


My approach is to simply do this:

   try:
       # redirect input() to raw_input() like Python 3
       input = raw_input
   except NameError:
       # no raw input, probably running Python 3 already
       pass


What do you think? Any better alternatives?

Uli

That's the generic solution, see
http://python3porting.com/differences.html#input-and-raw-input .

In my experience, it seems that input's main function is to allow
beginners to learn the language, or to be used in short scripts. For a
serious application, either curses or moving the input to the invocation
arguments is often a better choice.
