You've read the entire file, leaving the file pointer positioned at the
end of the file.

You're trying to read the file again, but the file pointer is still
positioned at the end of the file, and there's no more left to read.
If you want to read it again, you'll need to reset the file pointer
back to the start of the file using in_file.seek(0).
