Anything enclosed inside the quotation marks is called a string in python. It can be in either single quotes, double quotes, or triple quotes. Strings are immutable however, it supports indexing and slicing in addition to concatenation and repetition. The string has a maximum method compared to other data types. It supports 45 methods in […]
You can build your own YouTube downloader under five lines of code. Python has huge free modules and libraries available. To build a YouTube downloader in python, we will use a module called pytube. In this tutorial, I assume that you already have installed python version 3 and above on your machine and have some […]
Introduction The practical python paper wasn’t easy for my students. It’s been quite challenging to learn coding in the school since they get access to computers only during class hours and sometimes on weekends. Learning to code need consistent practice. My students get to practice one to two hours a week which makes the coding […]
Error and Exception handling blog post here Question 1: Perfect division function Write a function division() that accepts two arguments. The function should be able to catch an exception such as ZeroDivisionError, ValueError, or any unknown error you might come across when you are doing a division operation. Source code: Output: Question 2: Perfect division […]
Introduction Functions are used to organize code into blocks that we can reuse later. It makes the code more readable and modular. Moreover, it saves time when designing and running the code since it helps to keep code clean and unrepeated. We just need to call a function whenever a similar task needs to be […]
Introduction Loops in the program are used to iterate over the sequence of elements. In python, there are two primitive loops commands i.e. for loop while loop There are four practice questions and two coding challenges to give a good practice on loops in python. Question 1: Sum of numbers Write a program to find the sum […]
A palindrome number or a string is a word, number, phrase, or sequence that reads the same backward as forward. For example, Malayalam is a word that can be read the same backward as forward. Similarly, with regard to numbers such as 1001, 1221, etc is also a palindrome number. The source code displayed below […]
Introduction The conditional statements in programming languages decide the direction of the flow of program execution. It is used for decision-making. In Python, there is no switch or case statement like in other programming languages to make decisions in the program. However, it has if, elif, and else statement to make a decision. The decision […]
There are seven different types of arithmetic operators used in python. And it is particularly used for mathematical computations. Here are the seven different types of operators; Addition (+) Subtraction (-) Division (/) Multiplication (*) Exponents (**) Floor division (//) Modulus (%) To explore more on an arithmetic operator, check here Question 1: Write a […]
