range: return a range of integers

range returns a tuple of integers defined by the specified interval and stride.

range(stop)                             # equivalent to range(0, stop)
range(start, stop)                      # equivalent to range(start, stop, 1)
range(start, stop, step)

range requires between one and three integer arguments. With one argument, range(stop) returns the ascending sequence of non-negative integers less than stop. With two arguments, range(start, stop) returns only integers not less than start.

With three arguments, range(start, stop, step) returns integers formed by successively adding step to start until the value meets or passes stop. A call to range fails if the value of step is zero.

list(range(10))                         == [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
list(range(3, 10))                      == [3, 4, 5, 6, 7, 8, 9]
list(range(3, 10, 2))                   == [3, 5, 7, 9]
list(range(10, 3, -2))                  == [10, 8, 6, 4]
