# Number in range

OSCC · Python, Math · Sep 15, 2020

Checks if the given number falls within the given range.

• Use arithmetic comparison to check if the given number is in the specified range.
• If the second parameter, `end`, is not specified, the range is considered to be from `0` to `start`.
```def in_range(n, start, end = 0):
return start <= n <= end if end >= start else end <= n <= start```
```in_range(3, 2, 5) # True
in_range(3, 4) # True
in_range(2, 3, 5) # False
in_range(3, 2) # False```
