Beginners' Python

Workshop

• Programming Background (secret program flow)
• Installing Python
  • VSCode and Python Extension
• History of Python
• Rationale
• Activity 0 - Intro to the REPL
• Hello World
  • Intro to the REPL
• Primitive Data-Types (int, float, string, bool)
• Operators
  • REPL as a calculator
• Variables
• Moving into file-based programs
• Input (Type Casting, F-Strings)
  • Introducer bot
  • len() for length of name, in f-string
  • Number entry and odd / even checker
• Conditions
  • FizzBuzz checker (non-looping)
• Simple Loops
  • for-range fizzbuzz loop
• Activity 1 - Interactive User System
• Lists (indexing)
  • play around in the repl
  • select from input as a fake user id log in
• Advanced Collections (Dictionaries, Sets, Tuples)
  • username / password based entry to a system
• Loops (for, while, break, continue)
  • list all users on screen (then users made before / after)
  • build our own REPL!
• Functions (default args)
  • separate concerns (user inputselection vs action, move out into separate functions for each action)
  • Don't repeat yourself - user authentication repeated for different login moves
  • (aside, recursion and fibonnaci sequence)
• Modules
  • random number guesser
• External File Interaction
  • Writing calculations to a file
  • Reading inputs from a file
• Activity 2 - Turtle Spirograph
  • Moving the turtle
  • Repeating to build a pattern
• Classes
  • Spiro Class (position, turn, angle, acceleration factor)
  • Spiro Pivot Class (represents centre of page, can have connected spiros)
• Activity 3 - Scripting & Scraping
  • Installing Packages from PyPI via pip (svg-turtle)
  • Get blog names, and convert to hyphenated (a-z0-9-) (beautifulsoup4)
  • Convert to two numbers, representing spiro size, and one more representing acceleration (0.5 - 1.5
• Exceptions
  • urllib wrong URL
  • reading a missing file (config.txt - used to configure end point and css selector text search)
  • writing to a file that already exists (just the new name for now), accidentally overwritten, enable createnew
  • handle already existing file (overwrite save file function with y/n prompt)
  • write out svg files (svglib "reportlab<4")
• More Scripting
  • File conversion and renaming (append OS datetime)
• Advanced
  • Complex Numbers
  • Structured Pattern Matching
  • Lambda Expressions
  • global / nonlocal keywords
  • List Comprehension
  • Generators / Coroutines
  • For-Else Loops
  • Mutable default arguments
  • Classes
  • Iterables
