What is Python
 Powerful Dynamic Programming Language
 Uses Whitespace
 Everything Is A Object
 Very Portable
History of Python
 Created By Guido Van Rossum
 An improvement on ABC
 Open Source and Community Supported
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++
No GOTO
Control Structures
 Supports Nested If- Statements
 Does NOT support Switch Statements
 Has a different way of doing FOR loops
Default FOR loop
 Works similar to a For-Each loop
Ex:
for w in "Cat":
print(w)
OUTPUT :
C
a
t
FOR Loops
Java
for(int i = 5; i < 10; i++)
System.out.printf("%d\n", i);
OUTPUT:
5
6
7
8
9
Python
for i in range(5, 10):
print(i)
OUTPUT:
5
6
7
8
9
If it looks like a duck….
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
Subprograms
 Every function in Python returns a value
 Supports keyword parameters
 Allows for nested subprograms
Concurrency
 Python supports concurrency
 Since Python is interpreted, it can only handle logical
concurrency
Error and Event Handling
 Extensive Exception handling features
 Users can create their own errors through class objects
 Python doesn’t have native event handlers
