[Eclipse]

Code:

import string, random from random import randint def id_generator(size=6, chars=string.ascii_uppercase): return ''.join(random.choice(chars) for _ in range(size)) def random_no(n): range_start = 10**(n-1) range_end = (10**n)-1 return randint(range_start, range_end) f = open('list.txt', 'r+') def gen(): s = str(str(id_generator()) + str(random_no(2)) + 'c') if not s in f.readlines(): print(s) f.write(s + '\n') while True: gen()

How would I implement multi-threading in the example above? Say, two threads running simultaneously.
