A function is a block of code that performs a specific task. In this tutorial, we will learn about the Python function and function expressions with the help of examples.
- Create a function in Python. Write a program to create a function that takes two arguments, name and age, and print their value. Show Hint. Use the def keyword with the function name to define a function.
- Create a function with variable length of arguments. Write a program to create function func1() to accept a variable length of arguments and print their value.
- Return multiple values from a function. Write a program to create function calculation() such that it can accept two variables and calculate addition and subtraction.
- Create a function with a default argument. Write a program to create a function show_employee() using the following conditions. It should accept the employee’s name and salary and display both.
- Python function that prints a text. The statements in the function get executed only when we call the function. The function definition should be written before the function call.
- Python function that accepts two numbers as arguments and returns the sum. Functions can take arguments (one or more). Functions can return a value to the main method.
- Python function that accepts different values as parameters and returns a list. def myFruits(f1,f2,f3,f4): FruitsList = [f1,f2,f3,f4] return FruitsList output = myFruits("Apple","Bannana","Grapes","Orange") print(output)
- Python function that returns a dictionary. def myAnimals(a1,a2,a3): Animalgroup = {'Kitten':a1,'Puppy':a2,'Pup':a3} return Animalgroup output = myAnimals("Cat","Dog","Rat") print(output)
Jul 28, 2021 · In any programming language, functions facilitate code reusability. In simple terms, when you want to do something repeatedly, you can define that something as a function and call that function whenever you need to. In this tutorial, we shall learn about user-defined functions in Python.
A function is a reusable block of programming statements designed to perform a certain task. To define a function, Python provides the def keyword. The following is the syntax of defining a function.
Example. If the number of arguments is unknown, add a * before the parameter name: def my_function (*kids): print("The youngest child is " + kids [2]) my_function ("Emil", "Tobias", "Linus") Try it Yourself ». Arbitrary Arguments are often shortened to *args in Python documentations.
