🐍 Hello, World! in Different Ways (Python)

. Each example includes a short explanation.

This notebook demonstrates multiple creative ways to print "Hello, World!" in Python

1️⃣ Classic Print

The standard and most common way to print text in Python. print("Hello, World!") Hello, World!

2️⃣ Single Quotes

Python allows both single and double quotes for strings. print('Hello, World!') Hello, World!

3️⃣ Using a Variable

Store the message in a variable before printing. msg = "Hello, World!" print(msg) Hello, World!

4️⃣ String Concatenation

Combine multiple strings using the + operator. print("Hello, " + "World!") Hello, World!

5️⃣ Using join()

Join multiple strings from a list into one string. print("".join(["Hello", ", ", "World!"])) Hello, World!

6️⃣ f-String

Use formatted string literals (modern and recommended way). text = "World" print(f"Hello, {text}!") Hello, World!

7️⃣ format() Method

Older but still widely used string formatting method. print("Hello, {}!".format("World")) Hello, World!

8️⃣ Using sep Parameter

Customize how print separates multiple values. print("Hello", "World!", sep=", ") Hello, World!

9️⃣ List Unpacking

Unpack list elements directly into print function. print(*["Hello,", "World!"]) Hello, World!

🔟 Using ASCII Values

Construct the string using ASCII character codes.

print(chr(72)+chr(101)+chr(108)+chr(108)+chr(111)+",

"+chr(87)+chr(111)+chr(114)+chr(108)+chr(100)+"!") Hello, World!

1️⃣1️⃣ Lambda Function

Print using an anonymous (lambda) function. (lambda x: print(x))("Hello, World!") Hello, World!

1️⃣2️⃣ sys.stdout.write()

Directly write output to standard output stream. import sys sys.stdout.write("Hello, World!") Hello, World!

🔹 import sys sys is a built-in Python module. It provides access to system-level functions and variables. One important object inside it is stdout. Think of it like this: sys → system tools stdout → standard output (your screen / console) 🔹 What is sys.stdout? stdout means standard output stream It’s where Python sends output by default When you use print(), Python internally writes to sys.stdout

1️⃣3️⃣ Custom Function

Define and call your own function to print the message. def hi(): print("Hello, World!") hi() Hello, World!
