Answer 1

If you are using pathlib for filenames then you can use on both Windows and Linux (I came here for a windows answer):

python from pathlib import Path p = Path('~').expanduser() print(p)

Answer 2

it is your $HOME var in UNIX, which usually is /home/username.

"Your home" meaning the home of the user who's executing a command like cd ~/MyDocuments/ is cd /home/user_executing_cd_commnd/MyDocuments

Answer 3

Unless you're writing a shell script or using some other language that knows to substitute the value of $HOME for ~, tildes in file paths have no special meaning and will be treated as any other non-special character.

If you are writing a shell script, shells don't interpret tildes unless they occur as the first character in an argument. In other words, ~/file will become /path/to/users/home/directory/file, but ./~/file will be interpreted literally (i.e., "a file called file in a subdirectory of . called ~").

Used in URLs, interpretation of the tilde as a shorthand for a user's home directory (e.g., http://www.foo.org/~bob) is a convention borrowed from Unix. Implementation is entirely server-specific, so you'd need to check the documentation for your web server to see if it has any special meaning.
