Not a problem if you write them one after another. Besides which, any decent editor will have a command to go directly from the function call to the function definition, so I really don't see this as a problem. > The only reason to use such a technique in Python is if you want to > call the function if the program is run from the command line, and > also call the same function if the program is imported from another. Or if your main "routine" has variables, and you don't particularly want them polluting the module's global namespace. > In which case, use a name that is descriptive, not "main". "main" is descriptive in that it clearly designates the entry point of the script to anybody accustomed to such terminology. But there is certainly no reason it needs to be "main", and in fact I only used that for the example. In an actual script I would use whatever seems appropriate.
