Python is used for scripting, web development, data analysis, and many AI tools. This first lesson starts with a much smaller goal: display a line of text.
If you still need an editor or interpreter setup, the original setup article (Chinese) is linked here for reference. Use a supported Python 3 installation.
Hello, World
print("Hello, World!")Run the file in your editor or with the Python interpreter. The console displays:
Hello, World!
The parentheses contain the argument passed to print. Quotes mark a string literal; the quote characters themselves are not printed. Single quotes work too, as long as the opening and closing marks match:
print('Hello, World!')print displays output and normally adds a newline. It does not return the printed text as its function result; its return value is None. We will explore variables and return values in later lessons.
A small exercise
print("I can learn Python one step at a time!")Change the sentence and run it again. If you see a syntax error, check the parentheses and matching quotes. Learning the basic syntax is only a start, but being able to run a tiny program makes the next lesson much easier.
