Where to write?

You can use any Notepad or Text editor for writing your Python program. But there are May IDEs available to help us with auto fill the code snippet or help us with formatting the code and check for any syntax errors.

Your first Python program

# This is my first Python code
# To print Hello world in the console
print("Hello World")

Save the above file in any folder with the name helloworld.py

.py is the file extension used to identify the file is Python script
