  • What are Python Negative indexes?

    Introduction to Python Negative indexes In Python, negative indexes allows you to access elements of sequences (like lists, tuples, or strings) from the end of the sequence, rather than from the beginning. This is a convenient feature because it lets you easily refer to elements at the end of a sequence without needing to know its length. How Negative…

  • Why do we use join() function in Python?

    The join() function in Python is a string method used to concatenate (join) a sequence of strings (such as a list, tuple, or other iterable) into a single string

  • How to use break statement in Python?

    The break statement in Python is used to terminate the execution of a loop (such as for or while) prematurely, meaning that it allows you to exit the loop before it has iterated over all elements or satisfied its condition.

  • What are Python’s built-in data types?

    Introduction to Python’s built-in data types Python’s built-in data types refers to the types of values that Python provides. Which is to represent different kinds of data. They are the fundamental types of values it uses to represent different kinds of data. These data types are fundamental for performing various operations and they are essential…

  • What are different attributes in Python?

    Introduction to different attributes in Python Attributes in Python of a class or variable can have different levels of visibility and accessibility.These levels are controlled using the global, protected, and private naming conventions. These conventions determine how variables or methods can be accessed from outside the class, module, or function. Python employs conventions and syntactic rules to indicate how…

  • What is the self in Python classes?

    Introduction to self in Python classes Python classes use the self convention in instance methods to refer to the specific object being manipulated or operated on. In other words, self allows you to access the attributes and methods of the current object, and it is used to differentiate between instance variables (attributes) and local variables within methods.…

  • What are control flow statements in Python?

    Introduction to control flow statements in Python Continue, break, and pass are control flow statements in Python, that are used to alter the flow of execution within loops or conditional statements. Here’s a breakdown of each: 1. continue: The continue statement is used to skip the current iteration of a loop and move to the next iteration. When Python encounters a continue statement inside a…

  • What are Python Docstrings?

    Introduction to Python Docstrings Python Docstrings are special strings that we use to explain the purpose of a code. It can be a method, a module, a class, a function or code. By using docstrings, we can explain how the specific code does, how it works and how to use it. Docstrings are a critical…

  • What are Python unit test?

    We can test the correctness of a small, individual units of code. Such as functions of code with the help of Python unit test. We can check if a functionality in a program works as expected. When we isolate it from the rest of the program. This helps us identify the bugs in the development…

  • What is Python slicing?

    Introduction Python slicing is a process by which we can extract information from a list, a sequence or a tuple. It will allow you to access a subset of information from a sequence without modifying the original data. Basic Syntax of Python Slicing: sequence[start:stop:step] Examples of Slicing: Basic Slicing on a List # Example my_list…
