Examples of how to check if a number is in a given interval using python:

### Check if a number is in an closed interval

Let's assume for example that that the goal is to test if x is in the closed interval [2, 6], example with x = 1:

`>>> x = 1`

`>>> 2 <= x <= 6`

`False`

example with x = 3:

`>>> x = 3`

`>>> 2 <= x <= 6`

`True`

example with x = 2:

`>>> x = 2`

`>>> 2 <= x <= 6`

`True`

### Check if a number is in an open interval

open interval ]2, 6[, example with x = 2

`>>> x = 2`

`>>> 2 < x < 6`

`False`

### Check if a number is in an half-open interval

Half-open interval t ]2, 6], example with x = 6

`>>> x = 6`

`>>> 2 < x <= 6`

`True`

example with x=2

`>>> x = 2`

`>>> 2 < x <= 6`

`False`
