How to append another directory to an aliased `cd` command?

Question

I have aliased a long path in .bashrc file as

alias py="cd ~/Myprograms/Langs/workout/PythonScripts"

Now assume there is an another directory in PythonScripts say "basics"

How do I use the above alias without changing it, i.e, something like py/basics.

I tried this and it results in error

bash: py/basics: no such file or directory

How do I do this ?

Answer 1

This can't be done with bash aliases, but you can use functions:

py () {
  cd ~/Myprograms/Langs/workout/PythonScripts/"$1"
}

$1 is the first argument to the function. You can call it this:

py basics

Without any arguments, it would just cd to ~/Myprograms/Langs/workout/PythonScripts/.
