How do I create a list of random numbers without duplicates?
... = f1.readlines()
for i in range(50):
lines = random.sample(all_lines, 40)
This way, you only need to actually read from the file once, before your loop. It's much more efficient to do this than to seek back to the start of the file and call f1.readlines() again for each loop iteration.
