Buddy,
Please read the Python tutorial as distributed with Python. It
addresses this very issue in
one section.
May I also suggest picking up a "python for beginners" book to use
as a reference?
I had many of these questions when I first started writing Python a
few years ago and these
references were (and continue to be) indispensable...

Hi, I'm trying to append computed values to an output file at
defined solution intervals. All the documentation and tutorials
on python seem to write charachter strings instread of computed
values.
Here is a test case. Anyone have some tips on what to replace "
'Here I want the VALUES of t, r, l and d, but only can seem to get
a single string to work like this one!' " with to get the values
of t, r, l and d?
>>>t=0
>>>logfile = open('log.dat', 'w') # opens a file to write to
>>>logfile.write('t, r, l, d' "\n") #Hooray, this works, I
get a header!
>>>logfile.close() # should I leave it open for efficiency?
>>>while t<10:
>>> r=t-1*123
>>> l=342/r
>>> d=(87-r)*l
>>> t = t+1
>>> logfile = open('log.dat','a') # the 'a' allows you to
append to your file
>>> logfile.write('Here I want the VALUES of t, r, l and d, but
only can seem to get a single string to work like this one!' "\n")
>>>logfile.close()
Thanks in advance!
Buddy
