Python – Google Cloud Platform deploys python scripts

I’m figuring out how to deploy my script on Google Cloud Platform.
I have created a directory or folder with all the libraries in the script.py and /lib folders.

What I don’t get is setting up my app.yaml to run script.py (python 2.7) and access lib to when needed.

I

also don’t know if I need to make requirements.txt because I’m using a third-party library.

Here is everything I imported in script.py

import requests
import re
import mysql.connector
from urlparse import urlparse
from urlparse import urljoin
from bs4 import BeautifulSoup

Also, I have BeautifulSoup, requests, and mysql.connector in my lib.
I don’t know the others I think they are built-in python 2.7 because I can’t install them using pip.

By the way, I’m using Windows 10.

Apply.yaml

runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /lib/requests
  script: Scrape.app

handlers:
- url: /requests
  script: Scrape.app

handlers:
- url: /mysql/connector
  script: Scrape.app

handlers:
- url: /bs4/
  script: Scrape.app

cron.yaml

cron:
- description: "Scrape"
  url: /
  schedule: every 10 mins
  retry_parameters:
    min_backoff_seconds: 2.5
    max_doublings: 10

I get an error like this

Updating service [default]... failed.

From Handlers element Script line table:

A script: directive must be a python import path, for example,
package.module.app that points to a WSGI application. The last component of a script: directive using a Python module path is
the name of a global variable in the module: that variable must be a
WSGI app, and is usually called app by convention.

Note: just like for a Python import statement, each subdirectory
that is a package must contain a file named __init__.py

I recommend spending some time browsing Quickstart for Python App Engine Standard Environment in the code snippet, where you see the basic structure of a simple app.

The requirements.txt file can be used to specify a list of packages to install in the lib directory, as follows:

pip install -r requirements.txt -t lib

But this is not absolutely necessary, and packages can also be explicitly specified directly on the pip command line.
