The slowest possible method is to compare two files byte by byte. The fastest I’ve been able to come up with is a similar comparison, but instead of one byte at a time, you would use an array of bytes sized to Int64, and then compare the resulting numbers. Here’s what I came up with: … Read more
Loop over the file to read lines: with open(‘somefile’) as openfileobject: for line in openfileobject: do_something() File objects are iterable and yield lines until EOF. Using the file object as an iterable uses a buffer to ensure performant reads. You can do the same with the stdin (no need to use raw_input(): import sys for … Read more
