Assuming every line in input.txt contains a regular expression and you don't
care which one matches:
shakes = open("output.csv")
# you will iterate over the regex multiple times,
# so put them in a list
rattles = [line.strip() for line in open("input.txt")]
for line in shakes:
for expr in rattles:
if re.match(expr, line):
print line,
break # out of the for-rattles loop
# at the first matching regex
