How to compare the first line from multiple files Greetings, I'm new on the forum and relatively new to Python. I have been tasked at work with checking some files for consistency. What I need to do is verify that the first lines of a group of text files are identical. The files are all in the same directory. I know what the first line should be (or I can take the first line from the first file as the reference.) How would I go about doing this. Thanks in advance.

Easy to do. Open each file and read the first line into a variable. Then do something fun with this info, such as adding it to a dictionary and incrementing the value for that dictionary value each time you find that line. When you're done, you can check the length of the dictionary to see if there is more than one value, and then view the contents of the dictionary to find out what the unique values are.
