def name_of_function(): code A Python function should always start with the def keyword, which stands for define. Then we have the name of the function (typically should be in lower snake case), followed by a p
“def” is the keyword used to define a function in Python. “function_name” is the name you give to your function. It should follow the variable naming rules in Python. “parameter1”, “parameter2”, etc., are optional input values (also called arguments) that the function can accept...
Parameters are pieces of data wepass intothe function. The work of the function depends on what we pass into it. Parameters enable us to make our Python functions dynamic and reusable. We can define a function that takes parameters, allowing us to pass different arguments each time we call ...
Learn how to build a robust blockchain from scratch using Python. Explore blockchain fundamentals, consensus algorithms, and smart contracts through this blog.
In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
2. Define Functions Before Calling Them Move your function definitions to above the places where you call them. Remember: Python processes scripts from top to bottom! 3. Import Any External Modules If the undefined function lives in an external module, don’t forget to import that module first...
Classes are like a blueprint or a prototype that you can define to use to create objects. We define classes by using theclasskeyword, similar to how wedefine functionsby using thedefkeyword. Info:To follow along with the example code in this tutorial, open a Python interactive shell on you...

How to Define a Function: User-Defined Functions (UDFs) The four steps to defining a function in Python are the following: Use the keyword def to declare the function and follow this up with the function name. Add parameters to the function: they should be within the parentheses of the fu...
Unlike lambda forms in other languages, where they add functionality, Python lambdas are only a shorthand notation if you’re too lazy to define a function. (Source)Nevertheless, don’t let this statement deter you from using Python’s lambda. At first glance, you may accept that a lambda ...
