  1. Python By: Ben Hester

  2. What is Python • Powerful Dynamic Programming Language • Uses Whitespace • Everything Is AObject • Very Portable

  3. History of Python • Created By Guido Van Rossum • An improvement on ABC • Open Source and Community Supported

  4. Basics • Case Sensitive • Unlimited Integers • Arrays can contain elements of different types • Arrays can be broken into slices • Can be expanded with C or C++

  5. No GOTO

  6. Control Structures • Supports Nested If- Statements • Does NOT support Switch Statements • Has a different way of doing FOR loops

  7. Default FOR loop • Works similar to a For-Each loop Ex: for w in "Cat": print(w) OUTPUT : C a t

  8. FOR Loops Java Python for(int i = 5; i < 10; i++) System.out.printf("%d\n", i); OUTPUT: 5 6 7 8 9 for i in range(5, 10): print(i) OUTPUT: 5 6 7 8 9

  9. If it looks like a duck….

  10. Duck Typing • Python is a Dynamically Typed Language • Duck Typing is a subset of dynamic typing • In Python, methods don’t care what is passed as long as it works

  11. Subprograms • Every function in Python returns a value • Supports keyword parameters • Allows for nested subprograms

  12. Concurrency • Python supports concurrency • Since Python is interpreted, it can only handle logical concurrency

  13. Error and Event Handling • Extensive Exception handling features • Users can create their own errors through class objects • Python doesn’t have native event handlers
