Unlike many other languages, spaces and indents have meaning in Python. Statements are terminated by a line ending, and comments are introduced with a pound sign.
- [Instructor] Unlike most other…modern scripting languages,…whitespace is significant in Python.…Here in Komodo I've opened a working…copy of hello-main.py from…chapter two of the exercise files.…In Python a block is delimited by indentation.…There's no brackets or parentheses to match up just indents.…And so these two functions, main and message,…they have blocks which are associated with them…and that's the code that comprises the body of the function.…And you notice that they're indented…under the definition of the function,…the function declaration, the function definition.…
And so the main function has a function call…to the message function, and the message function…has a function call to the print function.…And you can tell that these are associated…because of their indentation.…Now if I take this message function,…well let's go ahead and run this…and you can see that it prints this Python…version and the version number and so…if I take this and I just add another print,…let's say print, line two,…and I save that and run it you see now…
