$13.$ Implement clamp

Read the specification of the function clamp in the module funcs. Implement this function according to its specification. Note that this function modifies the original list and does not return anything. Look at the test cases in tests.py if you are unsure.

Remember that you should never modify the loop$-$sequence in a for$-$loop. So your implementation should either loop over something else $($positions$)$ or use a while$-$loop. When you have implemented the function, test your answer with the test script before moving on to the next function.

def clamp$($alist$,$min,max$)$:

$"""$

Modifies alist so that every element is between min and max.

Any number in the list less than min is replaced with min. Any number

in the tuple greater than max is replaced with max. Any number between

min and max is left unchanged.

Examples:

If a $=[-1,1,3,5],$ clamp$($a$,0,4)$ changes a to $[0,1,3,4]$

If a $=[-1,1,3,5],$ clamp$($a$,-2,8)$ changes a to $[-1,1,3,-5]$

If a $=[-1,1,3,5],$ clamp$($a$,-2,-1)$ changes a to $[-1,-1,-1,-1]$

If a $=[],$ clamp$($a$,0,4)$ returns $[]$

Parameter alist: the list to modify

Precondition: alist is a list of numbers $($float or int$)$

Parameter min: the minimum value for the list

Precondition: min $<=$ max is a number

Parameter max: the maximum value for the list

Precondition: max $>=$ min is a number
