`if i` means `if i is considered true`. In this case we are talking about  
strings: "" is false and all other strings are true. So this is a way to  
say `if i is not the empty string`, effectively filtering out empty lines.
Perhaps using more meaningful names for variables makes the code more  
clear:

exploded_lines = [line.split() for line in lines if line]
