Python has four built-in data types data, set, tuple, dictionary, and list. These data types can store multiple collections of data. A set is an unordered collection of data, it is iterable, mutable, and has no duplicate elements. A tuple is an ordered collection of data but unlike a set, it is not mutable. A […]
Python tuple is an immutable sequence. The tuple is created with values separated by a comma. Since a tuple is immutable, we can’t add or delete its elements. If the tuple elements are not immutable, their properties can be changed. But, we can’t directly change a tuple element. We can create nested tuples. We can
When a function calls itself, it’s called a recursive function. In this tutorial, we will learn how to write Python recursion function. What is Recursion in Python? When a function is defined in such a way that it calls itself, it’s called a recursive function. This phenomenon is called recursion. Python supports recursive functions. Do
Python lambda function or Python anonymous function has no name. We can define an anonymous function using the lambda reserved keyword. The anonymous function scope is limited to the current scope where it’s defined. A lambda function can have one or more arguments but it can have only one expression. The expression is evaluated and
Exceptions are error scenarios that alter the normal execution flow of the program. The process of taking care of the possible exceptions is called exception handling. If exceptions are not handled properly, the program may terminate prematurely. It can cause data corruption or unwanted results. Python exception handling is achieved by three keyword blocks –

Numbers are used to store numerical values in the program. Python support three types of numbers – int, float, and complex. Python 2 also supports “long” but it’s deprecated in Python 3. In Python, numbers are also an object. Their data types are – int, float, and complex. There are built-in functions to create numbers
Python packages help us to manage modules and python scripts. They are normal directories with a init script – __init__.py. How to Create a Python Package? We can create a package by following below steps. Create the package directory – we can use terminal or Python IDE for this. Create __init__.py file – this is
Syntax of input() Function The syntax of input() function is: The prompt string is printed on the console and the control is given to the user to enter the value. You should print some useful information to guide the user to enter the expected value. Getting User Input in Python Here is a simple example

Python continue statement is used to skip the execution of the current iteration of the loop. We can’t use continue statement outside the loop, it will throw an error as “SyntaxError: ‘continue’ outside loop“. We can use continue statement with for loop and while loops. If the continue statement is present in a nested loop, it skips the execution
The break statement in Python is used to get out of the current loop. We can’t use break statement outside the loop, it will throw an error as “SyntaxError: ‘break’ outside loop“. We can use break statement with for loop and while loops. If the break statement is present in a nested loop, it terminates
