Answer:
Following are the program in the Python Programming Language:
my_lst=[] #set list
while(True): #set while loop
print("Enter stop, end or quit to stop the loop")
n=input("Enter the number of elements: ")
#get input from user
if(n=="quit" or n=="QUIT" or n=="stop" or n=="STOP" or n=="end" or n=="END"): #set if statement for break the loop
print(n)
break
else: #set else statement
a=int(n) #type conversion
for num in range(0,a): #set for loop
l=float(input("Enter the element for list: ")) #get elements of list
my_lst.append(l) #elements append to the list
print("List: ",my_lst) #print list
print("Average of the list:", sum(my_lst)/a)
#print average of the list
<u>Output</u>:
Enter the number of elements: 5
Enter the element for list: 1
Enter the element for list: 2
Enter the element for list: 3
Enter the element for list: 4
Enter the element for list: 5
List: [1.0, 2.0, 3.0, 4.0, 5.0]
Average of the list: 3.0
Enter the number of elements: STOP
STOP
Explanation:
Here, we set list data type variable "my_lst" then, we set the while loop statement and pass condition "True" and inside it.
- Then, we set a variable "n" and get input from the user in it.
- Then, we set the if statement and pass the condition is when user input stop, end, or quit then loop is break.
- Then, otherwise we set the variable "a" and the value of "n" is converted into the integer and store into "a".
- Then, we set the for loop statement inside the else statement which starts from 0 to n inside the loop.
- Then, we set the variable "l" which stores the elements of the list from the user in float data type.
- Then, we append the elements of the "l" into the list "my_lst" and end for loop.
- Finally, we print the list with message and then print average with message.
