The interactive interpreter


Data types

Strings Int bool float (only one real type) complex files


Attention plz

Python speaks now :

Do not tire yourself by writing type of the object

I will know it by myself ;)


Everything is an Object

>>> x = 'hello, world'>>> y = x.upper()>>> y'HELLO, WORLD!'

>>> import calendar>>> cal = calendar>>> print cal.month(2007,10)


Unusual Suspectslong — automatic promotion from int if needed

>>> x = 1024>>> x ** 50

Built-in data structures

Tuples – Fixed Length(1, 2, 3, “Hello”, False)

Lists[1, 2, 4, “Hello”, False]

Dictionaries{42: “The answer”, “key”: “value”}

Setsset([“list”, “of”, “values”])


FunctionsPython uses whitespace to determine blocks of code (please don't use tabs)

EX:def greet(person):

if person == “Tim”: print “Hello Master” else: print “Hello %s” % person


Classes

class MyClass: """This is a docstring.""" name = "Eric" def say(self): return "My name is %s" %

self.nameinstance = MyClass()print instance.say()


Modules

Any python file is considered a module

Modules are loaded from the PYTHONPATH


Exceptions

Also used for flow control – StopIterationExceptions are classes, and custom

exceptions are easy to write to store extra state

informationEX:

try: # Do stuff

except Exception, e: # Do something elseAll copyrights reserved for M. Gebreel(Harry Potter)
