Hello!  You can do rudimentary input with the functions:


Here's a sample interpreter session that shows how to use raw_input():

>>> def queryAndGreet():
...     name = raw_input("Please enter your name here: ")
...     print "Hello", name, "nice to meet you."
>>> queryAndGreet()
Please enter your name here: Devansh
Hello Devansh nice to meet you.

You'll probably want to use raw_input() to read in your strings; input()
has a more specialized purpose.

However, I get the feeling that your question asked for more control over
screen input and output.  If you want fine-tuned control over what happens
on the screen, you might want to look at the curses library:


The curses library will let you position characters at any coordinate of
your text screen.  You might need to learn a little more Python before
using it, but you'll definitely have some fun with it.


Finally, I wrote some hideously ugly code that works with the curses
library, if you want an example.  Take a look here:
