Reading keyboard input

[petethefeet]

Hey,

I'm learning Python and wanting to write a program the when I give a physical input I get an output.

For a start I'd like to press a key on the keyboard and get a Print output, but I can't seen to get off the ground.

Anyone give me the tools to get started?

Thanks

Pete

For Python 2:

Code: Select all

name = raw_input("What is your name? ")
print "Hello", name

In Python 3:

Code: Select all

name = input("What is your name? ")
print ("Hello", name)

raw_input returns a string. You can convert that to an integer for example like this:

Code: Select all

text = input("Pick a number: ")
number = int(text)
print ("Half of that is", number/2)

although to be entirely correct, it would be a good idea to catch the exception that will happen when the user types something that is not a number. This is left an an exercise for the interested reader

Your query is nothing to do with the subject of this rather old thread. You have two perfectly good threads on this subject already, one of which I have answered. Locking this one.
