if want change file can use fileinput.input inplace=true change file content:

import fileinput import sys line in fileinput.input("in.txt",inplace=true):     if line.strip():         w,i = line.split(",")         sys.stdout.write("{}\n\n".format(w)*int(i)) 

output:

word  word     cat  dog  dog  tiger
