Spotify Data Analysis Project using Python
Data analysis is an important field in business, research and many other areas. Among the many uses of this data, there are helping to make decisions and publish research papers. The weather can also be predicted based on data analysis too. You’ll learn how to perform exploratory data analysis by analyzing musical-related data sets within…
Read MoreDifference between Static and Class method in Python
Object oriented programming is a programming paradigm that relies on the concept of objects. These objects can have properties and methods, and can be manipulated via the language. It is sometimes referred to as “programming with objects” or just “OOP”, and emphasizes code reusability, encapsulation, information hiding, and dynamic binding of data through methods. Methods…
Read MoreDifferent uses of underscore in Python
1 – Using in interpreter When you execute the expression in the python interpreter it will store the result of last executed expression in special variable that is underscore (‘_’). 2 – Using in looping While using loops or iterating over iterable objects you can use underscore (‘_’) as a variable. 3 – Using in…
Read MoreUse of assert statement in Python
Syntax: Assert condition [Error Message] Example 1: assert statement without error message Example 2: assert statement with error message Example 3: assert statement with try & except Example 4: assert statement with function Above, square(10) will return 100, whereas square(-10) will raise an AssertionError because we passed -10.

Read MoreDifference between iterables and iterators in Python
Iterables Iterators Iterators can be iterable because both iterator and iterable can be iterated using for loop but iterable objects can not be iterator because next() method is not supported by iterable objects. Popular Posts
Read MoreDecorators and Generators in Python
Python implementation Generators Python generators are functions that are similar to normal functions, but use yield statements instead of return statements. A generator function returns the generator object with a sequence of elements, which we can iterate over. Element in a generator object can be accessed either by using the next() function or using a…
Read MoreAbstraction in Python
Abstract Class Why Abstraction is Important? In Python, a person usually abstracts data/classes to hide the irrelevant information. This helps to reduce complexity and increase application efficiency. Abstract Base Classes An abstract class is the first part of a development interface that can be used to apply common features and behavior to several related subclasses.…
Read MoreOOPs in Python
Object-oriented programming (OOP) is a programming paradigm based on the concept of objects which contains data or attributes and code or methods. Major oops concepts include Class, Object, Inheritance, Polymorphism, Data Abstraction, Encapsulation. Class Class is the user defined data type and it is defined using class keyword. It is a collection of similar type…
Read MorePython functions, Parameters, Arguments, args and kwargs
Python functions A function is a construct that helps us perform some action using a block of code (the body of the function), sometime based on input parameters. These functions can take different forms and can do a lot to allow your functional code base to be effective, To define a function, you use the…
Read MoreList comprehensions, break-continue, exception handling in Python
As we have learned for loop to walk through a sequence, and do something with each item, at least read some value from it. There is a scenario, similar to what we saw with the last example in the for-loop introduction, that involves making a new list from the result of doing an operation on…
