Python is a popular programming language known for its simplicity and versatility. In this blog post, I’ll walk you through the process of writing your first Python program. We’ll keep it simple by printing “Hello, World!” to the screen.
Step 1: Installing Python
The first step is to install Python on your computer. You can download the latest version of Python from the official website and follow the installation instructions for your operating system. Alternatively, you can use online editors like Repl.it or Trinket to run Python code in your browser without any installations.
Step 2: Writing the Python Code
Now, let’s write the Python code. A Python program is essentially a text file that contains instructions for the computer to execute. You can use any text editor, but be sure to save the file with a .py extension. For instance, you can name your file hello.py. Here’s the code for our “Hello, World!” program:
# This is a comment that explains the code
print("Hello, World!") # This function prints a messageIn this code, the # symbol marks the beginning of a comment, which is ignored by the computer. Comments are useful for documenting and explaining your code. The print() function is built-in and displays its argument on the screen. "Hello, World!" is a string enclosed by quotation marks.
Step 3: Running the Python Code
If you’ve installed Python on your computer, open a terminal or command prompt and navigate to the folder where you saved your file. Then, type python hello.py and press Enter to run your program. You should see the output “Hello, World!” on the screen. If you’re using an online editor, simply click the run button to see the result.
Conclusion
