问题 I want to construct a matrix of results for 48 GLMs (including model coefficients, R2, etc.). I though in calling the model objects by using a for loop which iteratively call them using paste() and mget() functions, which create a variable with the same name that the model object.

阅读更多关于 Is there a way to share common configuration using Paste Deploy?

问题 This is a pretty simple idea conceptually. In terms of specifics, I'm working with a pretty generic Kotti installation, where I'm customizing some pages / templates. Much of my configuration is shared between a production and development server. Currently, these settings are included in two separate ini files. It would be nice to DRY this configuration, with common settings in one place. I'm quite open to this happening in python or an an ini file / section (or perhaps a third, yet-to-be
