How to make my python function go to a specific folder path and run a command line

Question

I am trying to automate my build process. typically what I do is I go to a certain folder where my make scripts are at, open a CMD, type a command which is something like this "Bootstrap_make.bat /fic = Foo"

Now I want to do this from inside my python code. simple question is How to do this, i.e. how to; using python code. go to a certain path > and open a CMD > and execute the command"

here is what I’ve tried

def myClick():
subprocess.run(["cd ..ProjectsADASproj11embedded_envmake_scripts" ])
subprocess.run(["bootstrap_make.bat","/fic= my_software_variant"])

However I git this error :

Traceback (most recent call last):
File "C:UsersaelkhateAppDataLocalProgramsPythonPython310libtkinter_init_.py", line 1921, in call
return self.func(*args)

You can use subprocess.run, specifying the cwd (current working directory) kwarg.

You could use os.system().
https://docs.python.org/3/library/os.html

This code is assuming you are on Windows because you are running a .bat file and trying to open a CMD window.

import os

directory = './path/to/make/scripts'
buildCommand = './Bootstrap_make.bat'
buildArgs = '/fic = Foo'
# if you don't want a new cmd window you could do something like:
os.system('cd {} && {} {}'.format(directory, buildCommand, buildArgs))

# if you want a new cmd window you could do something like:
os.system('cd {} && start "" "{}" {}'.format(directory, buildCommand, buildArgs))
