What are Lambda Functions? In Python, we use the lambda keyword to declare an anonymous function, which is why we refer to them as “lambda functions”. An anonymous function refers to a function declared with no name. Although syntactically they look different, lambda functions behave in the same way as regular functions that are declared using the def keyword. The following are the characteristics of Python lambda functions: A lambda function can take any number of arguments, but they contain […]

Introduction When we think about repeating a task, we usually think about the for and while loops. These constructs allow us to perform iteration over a list, collection, etc. However, there’s another form of repeating a task, in a slightly different manner. By calling a function within itself, to solve a smaller instance of the same problem, we’re performing recursion. These functions call themselves until the problem is solved, practically dividing the initial problem to a lot of smaller instances […]

Introduction Functional Programming is a popular programming paradigm closely linked to computer science’s mathematical foundations. While there is no strict definition of what constitutes a functional language, we consider them to be languages that use functions to transform data. Python is not a functional programming language but it does incorporate some of its concepts alongside other programming paradigms. With Python, it’s easy to write code in a functional style, which may provide the best solution for the task at hand. […]

While you can put simple projects in a single file, most Python development projects will require multiple files to keep them manageable. That means you need a way to import one file into another. However, many Pythonistas find importing files confusing. Fortunately, it is easy if you know the difference between the various Python import statements. What is Importing? Importing refers to allowing a Python file or a Python module to access the script from another Python file or module. […]

In Python, there are two options/methods for running code: Interactive mode Script mode In this article, we will see the difference between the modes and will also discuss the pros and cons of running scripts in both of these modes. Interactive Mode Interactive mode, also known as the REPL provides us with a quick way of running blocks or a single line of Python code. The code executes via the Python shell, which comes with Python installation. Interactive mode is […]
