Newby question: Opening files not working about ios_system HOT 3 CLOSED

Python sends the argument of "open" directly to the "open()" function, without any pre-treatment. "open()" is a low level function, it does not check anything in the file name. So the function tries to open a file named, litterally, ~/Documents/testdir/test_text.txt and finds that it doesn't exist. You need to first expand the ~ to its full value, using os.path.expanduser("~/Documents/testdir/test_text.txt").

Alternatively, you can replace "~" with os.environ["HOME"], as in: open(os.environ["HOME"] + "/Documents/testdir/test_text.txt").

You could also use a local file path, rather than an absolute file path: open("test_text.txt").
