range not outputing last number

Question

Here is my code?

for i in range (10,20,2):
    print(i)

The output should be like this

But output is coming:

Why 20 is not coming?

This answer should help with the intuition: http://stackoverflow.com/a/4504677/3019689 — jez, Jan 06 '15 at 16:07
Did it ever occur to you to [RTFM](https://docs.python.org/2/library/functions.html#range)? *"If `step` is positive, the last element is the largest `start + i * step` **less than `stop`**"* (emphasis mine). It is even more explicit in [the tutorial](https://docs.python.org/2/tutorial/controlflow.html#the-range-function): *"The given end point is never part of the generated list"*. — jonrsharpe, Jan 06 '15 at 16:18

The second argument to range is exclusive (not included). You would need to set stop equal to 22:

for i in range(10,22,2):
    print(i)

to have 20 be in the output:

>>> for i in range(10,22,2):
...     print(i)
...
10
12
14
16
18
20
>>>

The range function always prints upto the max val

for i in range (10,22,2):
    print(i)

This will print as expected

The maximum value is not included. If you want 20 to appear, you'll need 20+1 as max value.
