Does anyone know how I can fix the following error? Error Message: "Import Error

ImportError: No module named _subprocess
I have installed the Google Cloud SDK for Windows and checked the box to get the bundled python installation (version 2.7.13) with it. Python Installation Check
Basically followed the instructions in the link below to get the Hello World application working in a local environment (up to step "Make a change"). https://cloud.google.com/appengine/docs/standard/python/quickstart
Now, the problem occurred when I added the statement import subprocess to the main.py file.
Note the exact problem is with line import _subprocess in module "subprocess.py". This is strange to me because if I try to run any basic python script (not using dev_appserver.py app.yaml to deploy the Google Cloud Environment) or if I just use the python interpreter directly from the console (Windows Command Prompt) I get no errors when trying toimport subprocess nor if I try to import _subprocess directly.
Import Statement from Console Python.
Here is the Hello World code (with added subprocess import):

import webapp2
import subprocess
class MainPage(webapp2.RequestHandler):
def get(self):
self.response.headers['Content-Type'] = 'text/plain'
self.response.write('Hello, World!')
app = webapp2.WSGIApplication([
('/', MainPage),
], debug=True)
Finally, my acquaintance had installed the same software earlier and gets no such error when running any application that uses this import statement.
Note: I am working on a Windows 10 machine.
