Hi, I feel very stupid, but I am stuck. I could try some workaround, but I want to understand what I am doing wrong.
The line: for line in open("parameterfile").readlines( ): print line.split() # trouble line The "trouble line" works fine in this example. It prints what I want, something which looks like lists of words: ['CT', 'CT', '268.0', '1.529']... etc. However, if I want to manipulate the individual list elements, I run into trouble. While print line.split()[0] still works, (it yields CT - first element), however, print line.split()[1] gives error: File "readatoms.py", line 103, in <module> print line.split()[1] IndexError: list index out of range Could you please tell me what's wrong. (I come from Perl background so Python seems out-of-the-body experience to me).
