This function defines a lambda function "add" which takes two arguments and returns their sum. Lambda functions are anonymous functions. Code: add = lambda x, y: x + y # Example usage: print(add(3,4)) Output: 7
No value is passed during the function call. Hence, default value is used for both parametersaandb. Python Keyword Argument In keyword arguments, arguments are assigned based on the name of the arguments. For example, def display_info(first_name, last_name): print('First Name:', first_name...
The abstraction of functionality into a function definition is an example of the Don’t Repeat Yourself (DRY) Principle of software development. This is arguably the strongest motivation for using functions. Modularity Functions allow complex processes to be broken up into smaller steps. Imagine, for...
In Python, after the function is created, we can call it from another function. A function must be defined before the function call; otherwise, the Python interpreter gives an error. To call the function, use the function name followed by the parentheses. Consider the following example of a ...

To define a function, we use the def keyword. The name of the function is what comes after the keyword. In this example, the function's name is greeting. So to call the function later in the script, we'll use the word greeting. After the name, we have the parameters of the functio...
