Python modulo operator (%) is used to get the remainder of a division. The modulo operation is supported for integers and floating point numbers. The syntax of modulo operator is a % b. Here “a” is dividend and “b” is the divisor. The output is the remainder when a is divided by b. If both […]

Python doesn’t support switch-case statements. There was a proposal to introduce Python switch case statements in PEP-3103 but it was rejected because it doesn’t add too much value. We can easily implement switch-case statements logic using the if-else-elif statements. However, we can implement switch-case like behavior in Python using custom code. Implementing Switch-Case in Python

Python yield keyword is used to create a generator function. The yield keyword can be used only inside a function body. When a function contains yield expression, it automatically becomes a generator function. The generator function returns an Iterator known as a generator. The generator controls the execution of the generator function. When generator next()

In this tutorial, we will learn about Python namespace, the scope of a variable and the rules for variable scope resolution. What is Python Namespace? Python namespaces are containers to map names to objects. In Python, everything is an object and we specify a name to the object so that we can access it later

We can create loops in Python using for loop and while loop. The for loop is used to iterate over a collection of items such as Tuple, List, Set, Dictionary, String, etc. Python for loop is always used with the “in” operator. The while loop is used to execute a block of code until the

Python Dictionary is a set of key-value pairs. A dictionary is an object of class dict. It’s an unordered collection means that while iterating the order of retrieval is not guaranteed. The dictionary keys and values can be of any type. They can also be None. The key and its value are separated using a
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
