Why might the write statement not work when writing to a text file in Python?

Question

Python

Hello, I'm learning Python, but when I got to the topic "Writing to text files", I ran into a problem. I wrote a program, saved it, ran it, and saw <<< and nothing else. And the main thing does not give errors.
Here is the code:

inputFile = open ('myfile.txt', 'r')
outputFile = open ('myoutputfile.txt', 'w')

msg ​​= inputFile.read(10)

while len(msg):
outputFile.write(msg
msg = inputFile.read(10) inputFile.close

()
outputFile.close()

Answer 1

How did you launch the program?
Judging by the description, you are looking at the window of the interactive python interpreter.
It shouldn't run when you run the .py file, so either you're running it wrong, or your python installation is crooked.

Answer 2

Launched in IDLE
