Send commands to CMD window?

Question

I'm looking to be able to send commands to the CMD (windows). I need to be able to send multiple commands and have them run on the CMD.

The specific commands I need to send are:

cd "C:\Python27\Scripts"
pyinstaller.exe --clean --win-private-assemblies -F --onefile –windowed --icon=app.ico app.py

Is this easily possible?

you can use a library that makes you able to send key to cmd or other — Mehrdad Dadvand

If you know the commands in advance, you can create a batch file and execute it as shown in my answer to a related question. — martineau

You don't need cmd.exe. Just use subprocess for this, e.g. subprocess.check_call([r'C:\Python27\Scripts\pyinstaller.exe', '--clean', '--win-private-assemblies', '-F', '--onefile', '--windowed', '--icon=app.ico', 'app.py'], cwd=r'C:\Python27\Scripts'). Passing the cwd option is necessary if that's where "app.ico" and "app.py" are located. — Eryk Sun

Very simple, you can either user the subprocess module for each command, or you can write all the commands to a bat file and execute that.

import os
script = '''
cd "C:\Python27\Scripts" 
pyinstaller.exe --clean --win-private-assemblies -F --onefile –windowed --icon=app.ico app.py
'''

with open('tmpscript.bat') as file_: 
    file_.write(script)
# either system or subprocess will work here
os.system('tmpscript.bat')
