So let’s get started with the definition of python function. What is python function? Function in python is a collection of related statements which are used to perform a specific task and return the result or value to the caller of the function. It basically breaks our code into smaller and modular chunks of code and

Python pass statement

Introduction to python pass statement: From last few articles we are learning about looping statements in python. Until now we have covered basic looping statements i.e for loop and while loop. Also we have covered topic break and continue statements in python using which we can decide whether to exit or continue the loop execution. Now let’s proceed further in this series and learn more about pass statement in python. Python pass statement is used as a placeholder in a program. Pass statement in python is a null statement i.e Nothing

Python break and continue statements

Introduction to python break and continue statements: In last few articles we have learned about looping in python and we have covered topics python for loop and python while loop. Basically these looping statements in python allows us to repeat the same task or code block efficiently. Using looping statements we can repeat the execution of code until the specified condition is satisfied. However sometimes we may come across some situations wherein: We want to terminate the loop execution and exit the loop without checking the

Python while loop

Introduction to python while loop: In computer programming, we may come across situations wherein we may require to execute same code repeatedly. Looping simply means execution of specific code again and again till the provided condition gets satisfied. There are many different ways of looping available in python. So in previous article we have covered python for loop and in this article we’ll be covering python while loop in detail. What is python while loop: Sometimes we can’t predict about when the test condition will be satisfied. Therefore

Python for loop

What is loop in python programming? In computer programming, In some situations we may require to execute certain code repeatedly. Looping simply means execution of specific code again and again till the provided condition gets satisfied. Python for loop is one of the most widely used loop statement. Typically Loop in python programming contains code blocks and test condition. During execution of program code blocks are first executed, Then the condition is verified. If the condition is not satisfied then same code block is executed again.

Python Flow control and If-else Statement

Flow Control Statements in python: In computer programming flow control statements are used to structure the program. These statements uses decision making, Looping and branching to structure the program. They basically determines the flow of program i.e In a program which line of code is going to be executed next is decided by these python flow control statements. In python there are many flow control statements such as, if…elif…else, While, for loop, Break and continue etc. and many more which we are going to learn in

Sets in python

Introduction to sets in python: In this tutorial we are going to learn python Set data type. So let’s first start with the definition of python set data type. It is an unordered collection of unique (non duplicates) immutable elements or items. Here an individual data item of set is called as an element or an item of set. set_variable = {1,2,3} In above example numbers 1, 2, 3 are known as the elements or items of set. How to create a Set in python? There

String concatenation and replication in python

Introduction to strings in python: String is a sequence of characters which includes letters, numbers and symbols like punctuation marks etc. In simple words string is the data in text format. Strings data type also contains white spaces in it. Text data is one of the mostly used data type in our day to day life. Let’s see one example of strings, In python “Apple” is a string and sentence “I ate an apple” is also a string, not only that but “123789” is also a

Identifiers and keywords in Python

What is meant by Identifiers and keywords in python? Both of these terms are related to naming conventions in python programming. In python code individual names given to the entities like variable, class, method etc. are known as identifiers. There are few words which are kept reserved by python language, which can’t be used as an identifiers. These reserved words are known as Keywords. That was the brief definition about identifier and keyword now let’s understand both of these terms thoroghly. Python Identifiers: In python program

Comments and indentation in python

How to add comments in python code: Comments are basically non-executable lines added in your program. While actual execution of program these commented lines are ignored by interpreter. Every programming language has its own way of inserting non-executable lines in the code. This provision of inserting comments in program is highly used in daily programming work. You can write anything as a comment in your program. Comments in python programming can be used to write a short description about the code. so that next time if
