Python program to print "Hello, World!"

This content has been archived. It may no longer be relevant

Here is a simple Python program to print “Hello, World!”:

print("Hello, World!")

To run this program, you can save it in a file with a .py extension, for example, hello_world.py, and then run it using a Python interpreter from your command line or an integrated development environment (IDE).

For example, if you save it as hello_world.py, you can run it from the command line like this:

python hello_world.py

This will output:

Hello, World!

Here’s a more detailed Python program that includes comments and additional print statements to demonstrate basic Python syntax and operations:

# This is a simple Python program to print "Hello, World!" and demonstrate basic syntax

# Print the classic "Hello, World!" message
print("Hello, World!")

# Print additional messages
print("Welcome to learning Python.")
print("Python is a versatile programming language.")

# Demonstrating basic arithmetic operations
print("Let's do some math:")
print("5 + 3 =", 5 + 3)
print("10 - 4 =", 10 - 4)
print("6 * 7 =", 6 * 7)
print("8 / 2 =", 8 / 2)

# Using variables
name = "Alice"
age = 30
print("My name is", name, "and I am", age, "years old.")

# Using a loop
print("Counting from 1 to 5:")
for i in range(1, 6):
    print(i)

# Conditional statements
if age > 18:
    print(name, "is an adult.")
else:
    print(name, "is not an adult.")

# Defining a function
def greet(person):
    return "Hello, " + person + "!"

# Calling the function
print(greet("Bob"))
print(greet(name))

Save this as detailed_hello_world.py and run it the same way as before:

python detailed_hello_world.py

This will output:

Hello, World!
Welcome to learning Python.
Python is a versatile programming language.
Let's do some math:
5 + 3 = 8
10 - 4 = 6
6 * 7 = 42
8 / 2 = 4.0
My name is Alice and I am 30 years old.
Counting from 1 to 5:
1
2
3
4
5
Alice is an adult.
Hello, Bob!
Hello, Alice!

So, that’s it. We hope you find it useful, we showed you different uses of print statements through comments, variables, loops, conditional statements, and functions in Python.
