print("Enter the Scores:")

total = []

while True:

num = int(input())

if num == -1:

break

total.append(num)

print("The average is:",(sum(total)/len(total)))

I wrote my code in python 3.8. Also, you have to be careful about adding -1 to the total. You don't want to count -1 in the average.

Write the necessary preprocessor directive to enable the use of the stream manipulators like setw and setprecision Additional No

<h3>What is manipulator?</h3>

Helping functions known as manipulators can change the input/output stream. It simply affects the I/O stream using the insertion () and extraction (>>) operators, not the value of a variable.

Special functions known as manipulators can be used in an I/O statement to change a stream's format specifications.

Operators who format the data presentation are known as manipulators.The application should contain the file iomanip.h to access manipulators.The manipulators endl, ws, ends, and flush are those without arguments.

Setw (val), Setfill (c), Setprecision (val), Setbase (val), SetIOS Flags (flag), and ResetIOS Flags are examples of manipulators with arguments (m).

Two categories of manipulators are typically in use: Specified and Unspecified.
