PYTHON BASICS
Counting with range
The range() function is incredibly flexible. You can tell it where to start and where to stop. Remember, Python stops just before the stop number.
How it reads
range(1, 4) generates numbers starting at 1 and stopping before 4 (1, 2, 3)
print(i) runs once for each of those numbers
Cloud tip: If you call range(stop), it starts at 0. If you call range(start, stop), it starts at start.
