> file = open(prefix1) > text = file.readlines() > len = len(text) You have redefined two built-in functions "file" and "len" in the first three lines. This is usually considered poor practice. Stick to meaningless variable names, it's safer (only joking). TypeError: 'int' object is not callable". This means that something you thought was a function is in fact an integer. It's helpful to post/look at the line number of the error; "how is this line failing", is much easier to answer than "how is my program failing". print len(fields) Here len is an integer, because you redefined it in line 3. I'm guessing this is the problem. -- http://mail.python.org/mailman/listinfo/python-list
