The last make task of the chapter, and the one where the program writes a whole file in a loop.

A teacher needs a program to quickly enter a list of students and their test scores, saving them all into a single text file. The teacher does not know exactly how many students took the test, so the program has to keep going until the teacher says they are finished.

Your task

Write a program that:

opens a text file named results.txt in write mode ("w"),
asks for a student’s name and reads it, where the answer STOP means that there are no more students,
uses a condition controlled (while) loop that keeps going as long as the name is not STOP,
inside the loop, asks for the student’s test score and reads it as a whole number, with int(),
writes the student’s name and score to the file, separated by a space, with a newline ("\n") at the end,
asks for the next student’s name and reads it, as the last thing inside the loop,
closes the file after the loop has finished,
outputs the message Results saved.

The tests also check your code: use int() to read the score.

The output

The question for a name, asked before the loop and again at the end of every repetition:

Enter student name or STOP to finish

The question for a score, asked once for every student:

Enter test score

And the last line, once the file has been closed:

Results saved

The file

results.txt holds one line per student, in the order they were entered, where NAME is the name and SCORE the score:

NAME SCORE

Every line ends with a "\n", the last one included. Anything the file held before the program ran is replaced. If the teacher types STOP straight away, the file ends up empty.

Example

Input:

Amira
72
Ben
45
Chloe
90
STOP

Output:

Enter student name or STOP to finish
Enter test score
Enter student name or STOP to finish
Enter test score
Enter student name or STOP to finish
Enter test score
Enter student name or STOP to finish
Results saved

results.txt afterwards:

Amira 72
Ben 45
Chloe 90

Ask each question with its own print, and read the answer with a bare input() on the next line, rather than passing the question to input(...). The questions are part of the output that is checked here, so their spelling, capital letters and punctuation count. So do the lines in the file.

Help! My code doesn't work!

Make sure that you check for the following things:

The file is opened once, before the loop, and closed once, after it. Open it in "w" mode inside the loop and every student wipes the one before.
The first name is read before the loop, so the condition has a name to check the very first time.
The next name is read at the end of the loop body. Forget it and the loop never ends.
STOP is compared exactly, in capital letters: name != "STOP".
The score goes through str() before it is joined onto the name, and every line ends with "\n".
Results saved is not indented, so it is printed once, after the loop.
