How to open adb shell and execute commands inside shell using python

Issue

I am trying to execute adb shell commands in python using subprocess.Popen

Example: Need to execute 'command' in adb shell. While executing manually, I open the command window and execute as below and it works.

>adb shell
#<command>

In Python I am using as below but the process is stuck and doesn't give output

subprocess.Popen('adb shell <command>)

Tried executing manually in command window, same result as python code,stuck and doesn't give output

>adb shell <command>

I am trying to execute a binary file in background(using binary file name followed by &) in the command.

Solution

Found a way to do it using communicate() method in subprocess module

procId = subprocess.Popen('adb shell', stdin = subprocess.PIPE)
procId.communicate('command1\ncommand2\nexit\n')
