You can also process the lines and write them out to the new logfile
as you read them in first time around, rather than: read them in,
process them, write them out, read them in, process them, write them
out;
log_file=open("old_log_file","r")
output_file=open("new_log_file","w")
for line in log_file:
line=line.replace("<G_", "").replace(".", " ").replace("(", " ")
tokens=line.split()
tokens_5=tokens[5].rsplit("_",1)
output.file_write('%s %s %s\n' % (tokens_5,tokens[14],tokens[22]))
output_file.close()
log_file.close()
