The following code is in python.

import statistics as st #importing statistics which include mean function.

def average(lst): #function average.

   return st.mean(lst)#returning mean.

lst=a = list(map(int,input("\nEnter the list : ").strip().split()))#taking input of the list..

print("The average is "+str(average(lst)))#printing the average.

Output:-

Enter the list :

1 2 3 4 5 6

The average is 3.5

Explanation:

I have used the statistics library which includes the mean function that calculates the mean or average of the list.In the function average having lst as an argument returns the mean of the list lst.

Then taking lst input from the user and printing it's average.

(tco 3) what vbscript boolean operator could be used to replace the nested selection structure in this pseudocode? if empmedical
Leto [7]
You want both conditions to be true, so you can "And" them.
In vbscript, the and is written as "And" (not as && like other languages), so you get:

<span>If (empmedicalins = "y") And (empdentalins = "y") Then
    print empidnumber, emplastname, empfirstname
Endif</span>
