Each language has its own rules for organizing and formatting programs.
Most (but not all) programming languages start with a program header of some kind.
The program heading in Pascal is the line that starts with the reserved word program, followed by the identifier giving the name of the program, followed by input and output options inside parenthesis, and ending with a semicolon (;) as a statement separater.
program SimpleProgram (output);
“11 Each program unit normally consists of two parts: a specification, containing the information that must be visible to other units, and a body, containing the implementation details, which need not be visible to other units.” —:Ada-Europe’s Ada Reference Manual: Introduction: Language Summary
“12 This distinction of the specification and body, and the ability to compile units separately, allows a program to be designed, written, and tested as a set of largely independent software components.” —:Ada-Europe’s Ada Reference Manual: Introduction: Language Summary See legal information
You can designate a Python script by using the she-bang or hash-bang line as the first line of your source code.
#!/usr/bin/env python
or
#!/usr/bin/env python options
The hash-bang line gives the full path for the Python interpretter.
Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).
