Python classes and objects

-
The class is a structural material structure. Things have a lot of variables and have a tradition of them. Python class is created in the core class. An object is created using the classroom constructor. These are then described in the class sample.

                                                 

Python classes/shapes:

Python is the product of the product. Nearly everything in Python is a thing, with its characteristics and methods. A class is like a constructor, or "ready" to create objects.

Create a class:

To create a classroom, use the key class

For example:

Create a class called MyClass, which has properties called x:

    class MyClass:

    x = 5

Create Object:

Now we can use myClass's name in the class to create elements

For example:

Create a name called P1, print value x:

     p1 = MyClass()

     print(p1.x)

__Init __ () Function:

Examples of the early grades are the easiest method, not effective in real life applications.
Understanding the meaning of the class is to understand () the activities are included __init __.
All classes have a task named __init __ (), which always comes when the class starts.
Using __ __init () to set the value of the item object, or other activities that need to be done when the product is created

For example:

Create a class called a person, with __init __ () to set the value of the name and age:
methods of the product

 class Person:

     def __init__(self, name, age):
     self.name = name
     self.age = age

 p1 = Person("John", 36)

      print(p1.name)
      print(p1.age)

Object Methods:

Other items may include methods. Procedures for items in the product.
Let's do this in the classroom

For example:

work by pressing the finger scroll and the P1 product:


class Person:

     def __init__(self, name, age):
     self.name = name
     self.age = age

 p1 = Person("John", 36)

      print(p1.name)
      print(p1.age)

The self Parameter:

Self-reliance is a reference for a unique class and is used to make changes in the classroom.
You should not be called, you can call what you like, but it is the first of all the classroom work

For example:

class Person:

  def __init__(mysillyobject, name, age):
    mysillyobject.name = name
    mysillyobject.age = age
def myfunc(abc):
    print("Hello my name is " + abc.name)
p1 = Person("John", 36)
p1.myfunc()

Modify Object Properties:

Use the word Mysillyobject ABC instead of you:
Description of properties of substances
You can change the properties of the following

For example:

P1 at 40
p1.age = 40

Attributes of deleted items:


You can remove the properties of the substance by using the keyword

For example:

Remove the age of the item P1:
del p1.age

Deleted items:

You can delete an item by using the keyword

For example:

Remove the item from P1:

Python – Functions

-
Functions is a structured and reusable organization that is used to perform only practical action. The  Python  Function will regularly make your application and a higher level of reuse. As you have already learned, Python offers many local functions such as print (), etc., but you can also create your own work. These staff are called user-defined. Defining a Function You can describe jobs to pay for necessary work. Here are some simple rules to describe Python’s activities. The types of activity begin with the main language followed by the name of the job and the cards (). All borders or panels should be placed inside. You can also do the holes in these articles. The first evidence of action can be voluntary training – documented work document or document. The pulse code for each function starts with a clot (:) and goes backwards. The return statement [presentation] deletes the action, submitting it voluntarily to the applicant. Evidence of return w...

What is Django in python?

-
Django is a high level of  Python  that promotes rapid development and clean and elegant design. Django facilitates the creation of web applications faster and less. Django is an open free application system in Python. The design is far beyond the scope of facilitating development. They contain and allow you to create applications or locations from existing sources rather than scratch. Django in Python: This is how websites - even simplified by one person - they still have features such as waiting support, management and management, contact forms, comment boxes, uploading files and more. In other words, if you create scratches, you will need to improve these parts alone. When you use this structure, these sections are built, which you do not fit properly to fit your site. The official website describes Django as a " python web-based web site that promotes rapid development and pure design, developed by experienced developers, has a lot of improvements, so that you c...

Python Shallow Copy and Deep Copy

-
In this article, you’ll learn about shallow copy and deep copy in Python with the help of examples. Table of Contents Copy an Object in Python Copy Module Shallow Copy Deep Copy Copy an Object in Python: Python, we used the operator = to make a copy of the item. You might think this creates something new; This does not mean that it creates a new trend in the original reference materials. Let's take an example to make old_list calls and references to the use of new items_list = the employer. Example 1: Copy number = Operator old_list = [[1, 2, 3], [4, 5, 6], [7, 8, 'a']] new_list = old_list new_list[2][2] = 9 print('Old List:', old_list) print('ID of Old List:', id(old_list)) print('New List:', new_list) print('ID of New List:', id(new_list)) When we implement the old program, productivity will be: Old List: [[1, 2, 3], [4, 5, 6], [7, 8, 9]] An ID of Old List: 140673303268168 New List: [[...
