Classes and inheritance in python on python hunter by Pran Sukh.

Class inheritance is powerful concept of Object Oriented Programming. In this post some basic examples will consolidate the concept on inheritance. 


Single Inheritance:-

class Parents:
    def methodParents(self):
        print("methodParents")

    
class Child(Parents):
    def methodChild(self):
        print("methodChild")

obj = Child()
obj.methodChild()
obj.methodParents()


Multiple Inheritance:- 
 1

class GrandParents:
    def GrandParentsMethod(self):
        print("Grand Parents are providing ethics")

    
class Parents():
    def ParentsMethod(self):
        print("Parent Are paying fee")

class Child(Parents,GrandParents):
    def ChildMethod(self):
        print("Child is studying")



class Main(Child):
    def mainMethod(self):
        print("main Method of Main")

obj = Main()
obj.mainMethod()
obj.ChildMethod()
obj.ParentsMethod()
obj.GrandParentsMethod()


Multilevel Inheritance:-

class Parents(GrandParents):
    def ParentsMethod(self):
        print("Parent Are paying fee")

class Child(Parents):
    def ChildMethod(self):
        print("Child is studying")

obj=Child()
obj.ChildMethod()
obj.ParentsMethod()

obj = Parents()
obj.GrandParentsMethod()
obj.ChildMethod()  #error

obj = GrandParents()
obj.ParentsMethod()  #error

obj = GrandParents()
obj.ChildMethod()  #error

Understanding the usage of underscore( _ ) of Python for beginner. On Python Hunter

Introduction: Just like you, a newbie in python scripting language, me too was confused about lot of new things in python that are not valid or available in other languages like Java, .Net etc. Just like other things i had seen the use of '_' underscore in python, at beginning level that flabbergasted me for a while.      With some research and practice i have summarised the following usage of '_' underscore in python. Hope you will find it helpful at beginning level. First Usage : Hold the previous output value. When used in interpreter. 1 2 3 4 5 6 7 _ = input () # For example you typed '5' print (_) # This will print '5' print ( int ( _ ) * int ( _ ) ) # This will print '25' print ( int ( _ ) + 10 ) The above will print '15', because last input was "5" and in above   line of code is producing '25' as output but not being handl

XML, XSLT info by pran sukh on Python Hunter blog.

What is XML? Many computer systems contain data in incompatible formats. Exchanging data between incompatible systems (or upgraded systems) is a time-consuming task for web developers. Large amounts of data must be converted, and incompatible data is often lost. XML stores data in plain text format. This provides a software- and hardware-independent way of storing, transporting, and sharing data. XML also makes it easier to expand or upgrade to new operating systems, new applications, or new browsers, without losing data. With XML, data can be available to all kinds of "reading machines" like people, computers, voice machines, news feeds, etc. XML:- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 <?xml version="1.0" encoding="UTF-8"?> <bookstore> <book category= "cooking" > <title lang= "en" > Every

XSLT applyTemeplate tag by pran sukh on Python Hunter.

XSLT is used for presenting XML data in well structured way and in eye appealing sense. In XSLT we can define different templates and maintain criteria for XSLT processor to parse the XML data in and apply different template for different XML tags. Lets examine following example XML DATA. 1 2 3 4 5 6 7 8 9 10 <student id= "1" eCode= "e1" > <firstName> Python 1 </firstName> <lastName> Hunert 1 </lastName> <dob> <day> 01 </day> <month> Jan </month> <year> 1991 </year> </dob> <course> Programmer </course> </student> In above XML data we want to present student id with dark background and eCode with red background colors, First Name in blue color, last name in green color and date of birth in different modes, so it will look like this. Source File:- XML_DATA.xml 1 2 3 4 5 6 7 8 9 10
