Get started with Python

Аннотация

Our Hello World program is very simple, it only needs two lines. The fi rst line begins with a ‘shebang’ (the symbol #! – also known as a hashbang) followed by the path to the Python interpreter. The program loader uses this line to work out what the rest of the lines need to be interpreted with. If you’re running this in an IDE like IDLE, you don’t necessarily need to do this. The code that is actually read by the Python interpreter is only a single line. We’re passing the value Hello World to the print function by placing it in brackets immediately after we’ve called the print function. Hello World is enclosed in quotation marks to indicate that it is a literal value and should not be interpreted as source code. As expected, the print function in Python prints any value that gets passed to it from the console
