[Tutor] file operations and formatting

[andy surany]

Hello list!

This should be an easy question.... but I haven't found any good
examples in my search.

a=99.99 # a float
b='hello world'
file=open('junk.txt','w')

What I want is to write a and b to junk.txt with a space in between (I'm
using file.write).

I tried using a format to write, but that didn't work - mostly because I
think that I don't understand formatting as well as I should. So does
anyone have a good reference/tutorial for formatting?

TIA.
