I have tried the above command in Python interactive shell and expect to see the output inside the shell environment. However, it ends up with just some return values.
我应该做些什么来让在炮弹内印制的返回结果?

p = subprocess.Popen( pwd , stdout = subprocess.PIPE)
p.communicate() # returns (stdout, None)

import subprocess
import sys
subprocess.call( pwd , stdout=sys.stdout) # outputs results of `pwd` to stdout
