Question

Create a function min_mid_max which takes a list as its formal parameter and returns a new list with the following characteristics: element 0 contains the minimum value • element 1 contains the middle value (not the median -- which would require an average if the list had an even number of elements). If the list is even (e.g. [1,2,3,4]) the 'middle' value will be the right value of the two possible choices (e.g. 3 rather than 2). • element 2 contains the maximum value Notes: • You can only use Python syntax shown so far (even if you know more) • You cannot use any math library (we have yet to see this) • You should use the function sorted. Remember the function sorted does not change its input, it returns a new list. • You should only need to call sorted one time. print(sorted(3,2,1])) • You can use the function int (another built in function) to help determine the index of the middle value. This function takes a floating point (or any kind of number) and converts it into an integer (e.g.print(int(4.32)). This will allow you to treat lists with an even number of elements the same as a list with a odd number of elements. • If min_mid_max is called with an empty list, return an empty list. • If min_mid_max is called with 1 item that item is the min, mid, and the max • If min_mid_max is called with 2 items, the mid and the max should be the same • No need to worry about the incoming list being the value None

Answer 1

Follows are the code to this question:

def min_mid_max(myList):#defining a method min_mid_max that accept a list in parameter

if len(myList)==0:#defining if block that check list length equal to 0

return []#return empty list

s = sorted(myList)#defining variable s that uses the sorted method to sort the list

m = int(len(myList)/2)#defining mid variable that hold list mid value

return [s[0], s[m], s[-1]]#return list values

print(min_mid_max([1,2,3,4]))#use print function to call method

print(min_mid_max([]))#use print function to call method

print(min_mid_max([1, 2]))#use print function to call method

print(min_mid_max([1]))#use print function to call method

Output:

Step-by-step explanation:

In the given code, a method "min_mid_max" is defined, which accepts a list "myList" in parameter, inside the method if block is used, that check length of the list.

If it is equal to 0, it will return an empty list, otherwise, a variable "s" is declared, that use the sorted method to sort the list, and in the "m" variable, it holds the mid number of list and returns its value.

In the print method, we call the above method by passing a list in its parameter.
