The first program most people write while learning any programming language is called the "Hello, World!" program. It simply displays the text Hello, World! on the screen.
Here's how we write it in Python:
Now let's decode this program.
print(): This is a Python function that tells the computer to output something.- Parentheses
(): The computer will output whatever value or text is present inside the parentheses.
In this example, print("Hello, World!") tells the computer to output the text Hello, World! exactly as written. The quotes (" ") indicate that Hello, World! is text.
According to Python's rules, any text we want to output must be enclosed in quotes. This can be either a single quote (' ') or a double quote (" "). If we don't use quotes, Python will show an error.
Example:
For numbers, we don't need to use quotes:
Now, what if we use quotes for numbers? Let's try it:
Notice that Python still outputs 5 successfully. However, Python treats "5" as text, not as the number 5, because it is enclosed in quotes.
Note: Python is case-sensitive. If you write
Print("Hello, World!")with an uppercase P, It will show an error.
Try it:
