What's in store for Python 2?

This may change if we end up needing more or less time for certain topics.

  • Class 7: Review & reading from/writing to files
  • Class 8: More file operations, argument parsing & list comprehension
  • Class 9: Error handling
  • Class 10: HTTP requests
  • Class 11: Intro to Python frameworks & object-oriented Python
  • Class 12: Your own app with Django!

(note: Python 1 series included classes 1-6)

Working with files

Have lots of files you need to combine, extract data from, clean up, rename or format into a nice report? We can do that!

Errors! Why they happen & what to do about them

We don't want users (or ourselves) to see mysterious errors at runtime 


                        Traceback (most recent call last):
                        File "", line 1, in 
                        TypeError: 'type' object is not iterable
                        >>>

We want to provide fallback code or a useful error message 


                        try:
                            for item in list:
                                do_really_cool_thing()
                        except:
                            print("Oh noes! Something went wrong with an item:"")
                            print(item)

HTTP requests

"Hypertext transfer protocol" sounds like it's from 1995, but it's still the way data gets around on the Web!

We'll learn how to use the requests module to get data from external sources, like APIs


                        import requests
                        r = requests.get('https://api.github.com/users/lizkrznarich')
                        print(r.status_code)
                        200
                        print(r.json())
                        {'login': 'lizkrznarich', 'id': 8026886, 'node_id': 'MDQ6VXNlcjgwMjY4ODY=', 'avatar_url': 'https://avatars.githubusercontent.com/u/8026886?v=4', 'gravatar_id': '', 'url': 'https://api.github.com/users/lizkrznarich', 'html_url': 'https://github.com/lizkrznarich', 'followers_url': 'https://api.github.com/users/lizkrznarich/followers', 'following_url': 'https://api.github.com/users/lizkrznarich/following{/other_user}', 'gists_url': 'https://api.github.com/users/lizkrznarich/gists{/gist_id}', 'starred_url': 'https://api.github.com/users/lizkrznarich/starred{/owner}{/repo}', 'subscriptions_url': 'https://api.github.com/users/lizkrznarich/subscriptions', 'organizations_url': 'https://api.github.com/users/lizkrznarich/orgs', 'repos_url': 'https://api.github.com/users/lizkrznarich/repos', 'events_url': 'https://api.github.com/users/lizkrznarich/events{/privacy}', 'received_events_url': 'https://api.github.com/users/lizkrznarich/received_events', 'type': 'User', 'site_admin': False, 'name': 'Liz Krznarich', 'company': 'DataCite', 'blog': '', 'location': None, 'email': None, 'hireable': None, 'bio': None, 'twitter_username': None, 'public_repos': 17, 'public_gists': 4, 'followers': 10, 'following': 0, 'created_at': '2014-06-30T13:28:04Z', 'updated_at': '2023-01-05T12:47:53Z'}

Building web apps with Django

Django is a popular framework for building Python web apps quickly

We'll use it to build a small app that fetches data from an API and displays it in a web page.

What should I know before starting Python 2?

Python 2 builds on Python 1, so you should be familiar with the basics covered in that class:

  • Data types & expressions (strings, integers, floats, booleans)
  • Data structures (lists, dictionaries, tuples)
  • Defining functions
  • Calling functions & methods
  • Conditionals (if/then/else)
  • Loops (while & for)
