how to define reserved template for python file for eclipse
You can define the templates used in PyDev (both for code-completion and for new modules) in window > preferences > pydev > editor > templates.
Anything with the context 'new module' there will be shown to you when you create a new module (and you can have many templates, such as one for unittests, empty modules, class modules, etc).
Note that the templates are only presented when you create a module with Alt+Shift+N > pydev module (or file > new > pydev module), not when you create a regular 'file' (even if it ends with .py)
I need to use a default template for my files, such as first heading : description of file, author, shebang line and so on. But PyDev and eclipse don't do it for me.
When i want to create a new file in my project, how i have them?
