Function that steps numbers based on input?

Question

Is there a function in python that lets me input a number (i.e 3) and a beginning and end number and steps accordingly:

function (10, 21, 2) -> [15, 20]

function (0, 16, 5) -> [3, 6, 9, 12, 15]

Why does `0,16,3` give `[3,6,9,12,15]`, whereas `10, 21, 2` gives `[15, 20]`? — thefourtheye, Jun 08 '15 at 18:41
You mean like listing numbers in a range? That would be the `range` function. — TigerhawkT3, Jun 08 '15 at 18:41
Your example is contradictory. In the first example the 3rd parameter is "number of steps" and in your second example the 3rd parameter is "size of each step" — Cory Kramer, Jun 08 '15 at 18:42

Range is the function which does the same :

for a in range(0,16,3):
    print a

Better follow some tutorials these are very basics of python .

If you want to use in a for loop you want - range(<start>,<end>,<Step>)

You can accomplish your task using the range fucntion. The base syntax is:

range(start, end, step)
range(1, 10, 2) = [1, 3, 5, 7, 9]
range(1, 10, 5) = [1, 6]

Note that `range()` only returns a `list` in Python 2. It returns a `range` object in Python 3. – TigerhawkT3 Jun 08 '15 at 19:08
