Hi group, I have a basic question on the zip built in function.
I am writing a simple text file comparison script, that compares line by line and character by character. The output is the original file, with an X in place of any characters that are different. I have managed a solution for a fixed (3) number of files, but I want a solution of any number of input files. The outline of my solution: for vec in zip(vec_list[0],vec_list[1],vec_list[2]): res = '' for entry in zip(vec[0],vec[1],vec[2]): if len(set(entry)) > 1: res = res+'X' else: res = res+entry[0] outfile.write(res) So vec is a tuple containing a line from each file, and then entry is a tuple containg a character from each line. 2 questions 1) What is the general solution. Using zip in this way looks wrong. Is there another function that does what I want 2) I am using set to remove any repeated characters. Is there a "better" way ? Any other comments/suggestions appreciated. Thanks, Steven -- http://mail.python.org/mailman/listinfo/python-list
