Crafting Introduction for Python Functions
Description Paragraph
This article provides a detailed guide on defining functions in Python. From the basic syntax to practical examples, readers will learn how to define and use functions effectively in Python.
Explanation for the video
Embedded video for illustrating the concept of defining functions in Python will be provided in the article.
Key Concepts Explanation
Defining Functions
In Python, functions are defined using the def
keyword followed by the function name and parameters enclosed in parentheses. The function definition ends with a colon :
.
def add(a, b):
return a + b
Returning Values
Functions in Python can return values using the return
keyword. This allows the function to produce output that can be used elsewhere in the code.
def multiply(x, y):
return x * y
Hands-On Tasks
Explore the following tasks to practice defining functions in Python:
- Define a function named
calculate_area
that calculates the area of a rectangle given its length and width. - Implement a function
is_prime
that checks if a given number is a prime number.
