question about list comprehension - adriaanNL - Sep-09-2018
I am practicing for the python PCAP exam and i don't understand this excercise:
How many empty lines will the following snippet send to the console?
l = [[c for c in range(r)] for r in range(3)]
for x in l:
if len(x) < 2:
print()I do understand easy list comprehensions but not this one with c for c in range®.If someone could explain this I would be very thankful.
