I'm in python 3.7.3 on MacOS 10.14.5.
I found the os.chdir() to change the programs working directory. Now I need to learn how to access the current user's environment variables such as $HOME.
One contributor said that user.info contains the home directory, but I haven't found how to obtain that. Thank you.
These don't work: :-)
os.chdir("$HOME")
os.chdir("~")
os.chdir("$HOME")
FileNotFoundError: [Errno 2] No such file or directory: '$HOME'
Use
os.chdir(os.path.expanduser("~"))
The function os.path.expanduser
replaces the tilde with the user directory and works on Unix/Linux and Windows
$HOME
and ~
are shell syntax that expands into the user's home directory, not actual directory names by themselves.
Use os.environ
to access environment variables in Python:
os.chdir(os.environ['HOME'])
