how can I implement "cd" like shell in Python?

[Sergi Pasoev]

Do you mean to implement the cd command ? To what extent do you want to
implement it ? if what you want is just to have a script to change the
current working directory, it is as easy as this:


import sys
import os
os.chdir(sys.argv[1])

plus you could add some error-handling code.

'cd' is a shell built-in, because otherwise it would have no effect.

You can write a Python script that invokes os.chdir(), but that won't
have any effect on the shell that starts the script.

What are you trying to achieve?

To have a shell / python script interaction for cwd management, you can take
a look at autojump

Its a Python script + different shells glue.
