Folder and file organization for Python development

What is the best way to organize code that belongs to the same project in a Python development environment? What are the do and donts of Python project organization? Do you separate each class in a file?

Project A
   Classes
       "subsystem1"
           class1
           class2
           subsystem1Module
       "subsystem2"
       "utils"
       "etc"
   Tests
   Whatever
   etc?

Any suggestions? Oh, and please describe wha开发者_开发百科t are the (possible) problems of each type of organization.

What are considered best practices for organizing Python code?

There are not that many issues that are going to be applicable only to Python. This website: Software Configuration Management Patterns and the associate book describes some Source Code Management patterns.

The issues are described in the familiar patterns language so you should be able to find the information you need for your requirements. As with all patterns there is also discussion on the trade-offs.
