I find the W3School site to be more helpful initially. Then, if I need more detail and definition, I got to the official Python doc site (which, honestly, I find difficult to navigate).

W3 Schools:

• Python
  • User Input
• Reference
  • Built-In Functions
  • String Methods
  • List Methods | https://www.w3schools.com/python/python_lists_comprehension.asp | List Comprehensions]]

Python Site: python.org

• Standard Library Index
  • Built-In Types (& their methods, etc.)

If you do not want to preface all your script names with python3 to run them, your Python scripts should being with (note: your filesystem address may differ):

#!/usr/bin/python3

Here's an easy quick Python Web Server in your pwd:

python -m SimpleHTTPServer 8080

Pick a port. 8080 is random. Tab completion works for the module name (-m is for “module”). This allows you to transfer files anywhere on the network.

• Put your files in the subdir
• Spin up the Python web server
• Access that server by IP address: port number (192.168.0.101:8080) from any machine
• Download files from the server machine to the client machine
• Documentation: https://docs.python.org/2/library/simplehttpserver.html

If you use Python 3, you should instead write

python3 -m http.server 8080

Python3 http.server documentation: https://docs.python.org/release/3.0.1/library/http.server.html

Note: You may have to pip install pyftpdlib

python -m pyftpdlib

1. Ordered List ItemConnect to that machine's IP address with the port number shown.
2. Download anything. Navigate around.

Runs main() if file was not imported:

if __name__ == '__main__':
    main()
