Question
![Write a program which repeatedly reads numbers until the user enters "done". Once
"done" is entered, print out the count, sum and average of the numbers entered. If the
user enters anything other than a number, detect their mistake using try and except
and print an error message and skip to the next number.
1. Type the following code on your Python script.
1 count=0
2 total=0
3 while True:
4
try:
5
inp=input("Enter a number: ")
if inp == 'done":
6
7
break
8
num-float(inp)
count = count+1
10
total total num
11
mean = total/count
12
except:
13
print("\ninvalid input!")
continue
14
15 print("Count = (0), Sum=(1:2), Average = (2.2f) format(count, total,mean])
2. Run the script on the Python console and use the program. Try different inputs and
check the result. Also try to enter some non-numerical inputs to test the try/except
block of the code.
Page 7
3. Explain lines 6 and 7. What happens to the program when this if block is executed?
4. Explain what happens to lines 9, 10 and 11 every time the while block is executed?
5. When an error occurs within the try block, the program will proceed to execute the
except block as discussed in the previous experiments. Explain the statements within
the except block and briefly discuss what it does in the execution of the program.
