linux - How can I execute OS Commands with Python pexpect?

Question

I want to execute a python script, which switches to another user by automatically writing the user password. Both users have no root rights. After the login I want to execute the OS Commands "whoami" to check if the login was successful. Here's the code:

child = pexpect.spawn('su - otheruser)
child.expect_exact('Password:')
child.sendline('password')
print("logged in...")
child.expect('')
child.sendline('whoami')
print(child.before)

I want to print the output from the command to the console (just for debugging) but the output is like "b272' (a combination of random letters) and not the actual whoami user. How can I fix that?

Later I want to create from the switched user some files and so on. So basically, I want to execute OS Commands in a python script which is logged in an other user.
