# Sample Python Program # Python Tutorials - www.TestingDocs.com # Python Function to calculate area def calculate_area(length, width): return length * width # Main function def main(): # Get input from the user length = float(input("Enter the length of the rectangle: ")) width = float(input("Enter the width of the rectangle: ")) # Calculate the area area = calculate_area(length, width) # Display the result print(f"The area of the rectangle is: {area}") # Call the main function if __name__ == "__main__": main()
Explanation
Function Definition
calculate_area(length, width):
This function takes the length and width of the rectangle as arguments and returns the area.
Main Function
The main() function handles user input and output. The input() is used to obtain the user’s length and width.
The inputs are converted to float to handle decimal values.
The calculate_area() function is called with the user-provided length and width to compute the area.
The result is printed using an f-string for formatted output.
Program Execution
The if __name__ == “__main__”: block ensures that main() is called only when the script is executed directly, not when it is imported as a module in another script.
You can run this program in any Python IDE environment to practice it
