How do I write a simple Python script that is globally executable via a simple command (such as cd or pwd)?

I know the file has to be executable and in my $PATH. I know I can omit the python prefix when calling the file by specifying the interpreter. But then I still have to call the script using the ./script syntax.

I basically want to create a bunch of Python CLI programs stored ~/bin and have them behaving the same way as Bash scripts like cd and pwd.

export PATH="$HOME/bin:$PATH"

To see the changes in the current shell, you can then do . ~/.bashrc. The path should automatically be added in all new shells that you open. You can check by doing echo "$PATH" - you should see that it starts with /home_directory/bin:....
