Python has a built-in function called range that generates a sequence of numbers. range can accept 1, 2, or 3 parameters.
If one parameter is given, range generates a sequence of that length, starting at zero and incrementing by 1. For example, range(3) produces the numbers 0, 1, 2.
If two parameters are given, range starts at the first and ends just before the second, incrementing by one. For example, range(2, 5) produces 2, 3, 4.
If range is given 3 parameters, it starts at the first one, ends just before the second one, and increments by the third one. For example, range(3, 10, 2) produces 3, 5, 7, 9.
Using range, write a loop that uses range to print the first 3 natural numbers:
1
2
3
for number in range(1, 4): print(number)
