This means that the Python interpreter will run a file containing Python script regardless of what the extension of the file is. Note: The Python script doesn’t necessarily need an extension. For demonstration, we’ll add the Hello, World! code that we ran earlier to the newly created text file, which is: print (“Hello, World!”) To create a Python script, simply open a text editor on your system and add the Python code that you wish to use. Because a bigger project requires much more lines of code, it is desirable to create a Python script rather than typing it over and over again. Using Python interpreter is good enough for quickly executing some Python code. Hence, if you are adding an extra space just before the print keyword, you will get an error like this: > print("Hello, World!") File "", line 1 print("Hello, World!") ^ IndentationError: unexpected indentĬreating the Hello, World! Python Script Using a Text Editor Note: - While running the Python code, the Python interpreter accounts for the indentation. In front of the > prompt, type: print (“Hello, World!”) Let’s start with the traditional Hello, World! program. In case it is not there, you might want to reinstall Python on your system.Ĭomplete Python Bootcamp From Zero to Hero in Python Running the Hello, World!

The Python interpreter continues execution until instructed to stop by the exit() or quit() command. REPL stands for Reading the command, Evaluating and executing the command, Printing the output, and Looping back and repeating the entire process. It works on the REPL environment, which is also known as an interactive top-level shell. The Python interpreter is responsible for executing the Python scripts. To run a Python script, you need to first set up Python and ensure that you have a working Python interpreter.
