Python's indentation rules are pretty simple.  You need to indent all 
the contents of a for-loop, and the loop is over when you outdent back 
to line up with the for statement.  In your posting, you don't indent at 
all, so you'll get an error on the line following the for statement.

Now perhaps that's the fault of the way you're posting.  Easiest is 
usually to tell your email program to compose as plain text.

z=[]
f=open('C:/atextfile.txt')
for aLine in f:
     str=aLine
     a=str.split()
     z.append(a)
f.close()
print z


Now you mention writing to a file.  I hope you're not planning to write to the same file you're reading from.  Anyway,tell us more about what you want, and whether the print of z shows what you're expecting, or want.
