Intro to Python
- 1. Intro to Python CSSU Nov/28/2007 By Georgi Petrov & Atanas Dyulgerov
- 2. Outline What is Python Python Advantages Who uses Python Syntax & Semantics Data Structures Python Standard Library Demo 1 Object Orientation Demo 2
- 3. What is Python? interpreted, interactive, object-oriented programming language Widely used in the industry Cousin of Tcl, Perl and VB Used in web programming and in standalone applications
- 4. Python Advantages Elegant syntax Safe Object-oriented Powerful Portable Free
- 5. Python is simple print "Hello World!" #include <iostream.h> int main() { cout << "Hello World!"; } public class helloWorld { public static void main(String [] args) { System.out.println("Hello World!"); } } Python C++ Java
- 6. Python is fun & practical Lack of type declaration Huge library of modules Widespread use in industry Available for all the major platforms (Windows, MacOS, Linux, Unix, BeOS, Java)
- 7. Who uses Python Google NASA Rackspace Industrial Light & Magic
- 9. Syntax - Operators Comparison Operators ==, <, >, <=, >= Logical Operators Zero values are treated as “”, 0, None, 0.0, [] and {}
- 10. Data Structures Base Types integer, float, long integer, octal integer, hexadecimal integer, complex, character string, list, dictionary, tuples, file Collection types sequences & mappings Object system
- 11. Python Standard Library The greatest strengths of Python Hundreds of modules Examples Syntax: import email email , math , calendar , HTMLParser
- 12. Object Oriented Mechanism Similar to C++ and Java Supports multiple inheritance Polymorphism No private class members class Stack: def __init__(self,size): self.data = [None]*size self.size = 0 def push(self,item): self.data[self.size] = item self.size = self.size + 1 def pop(self): self.size = self.size - 1 return self.data[self.size] def is_empty(self): return self.size == 0 def is_full(self): return self.size == len(self.data)
- 13. Demo 1 Adjusting Apache to read Python Sample “Hello World” script
- 14. Object Orientation Defining classes class SomeClass: "Just some class...that's all." Adding data members and methods class SomeClass "Just some class...that's all." someNumber = 2131 def someFunction ( self ): return someNumber
- 15. Object Orientation Self Instantiating myObject = myClass() Calling and addressing myObject.someFunction() Deletion del myObject.someNumber
- 16. Object Orientation Constructors class AnotherClass: def __init__ ( self, anotherArgument ): self.anotherArgument = anotherArgument Single/Multiple Inheritance and Overriding class ParentClass: def print( self ): print “parent” class ChildClass ( ParentClass ): def print( self ): print “child”
- 17. Demo 2 Brief networking info Sockets SocketServer Framework Ports and Addresses Demo
