When we write a Python program and save that program into a file, that file we can call it as a Module. A module in Python is nothing but a group of statements and definitions, saved into a file. Each module has a purpose. Each module contains group of definitions or functions and statements, exported […]
In Python, Class methods and Static methods are two types of methods that are NOT bound to instances in the same way as regular methods. They are defined using decorators and serve different purposes. Class Methods (@classmethod) A class method takes cls as its first parameter, which refers to the class itself (not the instance). […]
In Python, constructors and destructors are special methods used to initialize and clean up objects of a class. Constructor: __init__ Method The constructor in Python is defined using the __init__ method. It is automatically called when a new object of the class is created. For example, # Vehicle.py class Vehicle: def __init__(self, type, color): self.type […]
We have discussed Truth Value testing in our previous Articles “Python – Truth Value Testing” and “Python – Truth Value Testing for Class objects“. Through this article, we will discuss customizing Truth Value testing. We can customize Truth value testing by defining __bool__ and __len__ functions. Initially, Python verifies the definition of _bool_ function; if […]
We have discussed Truth Value Testing in our previous Article, “Python – Truth Value Testing“; where we have discussed that Class objects are, by default considered True for Truth Value Testing. Through this article, we will discuss the Truth Value Testing for Class objects. Truth Value Testing for Class objects By default, Truth Value Testing […]
There are NO Access Modifiers in Python. Yes, what you READ is CORRECT. Python doesn’t have any Access Specifiers defined. All the defined members can access from anywhere in the program, within the defined scope. Some of the Programming Languages (C++, Java, C# etc,.) provides private, protected & public access modifiers to define the access […]
We have discussed about while Statement in our previous Article “Python – Control Flows – The while Statement“. The while Statement is useful to repeatedly execute the statements as long as the conditional expression evaluates to true. In this article, we are going to discuss another compound statement, the for statement. The for Loop The […]
We have discussed if Statement in our previous Article “Python – Control Flows – The if Statement“. The if Statement is one of the control statements in Python, used to control the flow of the Program depending on the conditional expression. The code is written inside the if Statement is going to execute only once […]
When we write the code in any language, we always write portion of the code to execute depending on certain condition(s). This will give more control and easy to manage the code. The statement which control the flow of the execution is control or conditional statement. One of such control statement is; the if statement. […]
Python provides an exception handling mechanism to handle the Exceptions when something went wrong in the Program. Python interpreter reads the code and throws an Exception when something went wrong; if the mechanism is provided to handle the Error, the Program execution continues, otherwise, the Program terminates. A very good example of an Exception is […]
