Python Hello World Project: Solutions and Explanations


Hello World: A classic first project; print "Hello, World!" to the console.

Input: None

Output:

Hello, World!

Solution 1: Basic Print Statement

Code:

# Solution 1: Basic Print Statement

# The print() function is used in Python to output text to the console.
# Here, we use it to print the phrase "Hello, World!".
print("Hello, World!")

Output:

Hello, World!

Explanation:

  • Uses the built-in print() function to directly output the text "Hello, World!" to the console.
  • This is the simplest way to achieve the desired output in Python.

Solution 2: Using a Function

Code:

# Solution 2: Using a Function

# Define a function named 'hello_world' that encapsulates the functionality
# to print "Hello, World!" to the console.
def hello_world():
    # This is the core logic that prints "Hello, World!" to the console.
    print("Hello, World!")

# Call the function 'hello_world' to execute the print statement.
hello_world()

Output:

Hello, World!

Explanation:

  • Defines a function hello_world() to encapsulate the print operation.
  • The function is called at the end to execute the print statement.
  • This approach is useful for code organization and reusability, especially if you want to use the "Hello, World!" output in multiple places or conditionally.

Note:
Both solutions achieve the same output, but Solution 2 provides a more structured way of writing code, which is helpful in larger projects.
