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`.
|
|
|
|
```py
|
|
def in_range(n, start, end = 0):
|
|
return start <= n <= end if end >= start else end <= n <= start
|
|
```
|
|
|
|
```py
|
|
in_range(3, 2, 5) # True
|
|
in_range(3, 4) # True
|
|
in_range(2, 3, 5) # False
|
|
in_range(3, 2) # False
|
|
```
