Let’s assume that your Python script is example.py:

import os
import time
import sys
import fnmatch
import requests
import urllib.request
from bs4 import BeautifulSoup
from multiprocessing.dummy import Pool as ThreadPool 
print('test')

You can use pipreqs to automatically generate a requirements.txt file based on the import statements that the Python script(s) contain. To use pipreqs, assuming that you are in the directory where example.py is located:

pip install pipreqs
pipreqs .

It will generate the following requirements.txt file:

requests==2.23.0
beautifulsoup4==4.9.1

which you can install with:

pip install -r requirements.txt
