On-demand imports, taken from mercurial
Delays loading of modules until they are actually used. Perfect for Python apps that need to be snappy like command-line utils. Source-code derived from mercurial.
To enable, write
import demandimport; demandimport.enable()
Imports of the following form will be delayed
import a, b.c import a.b as c from a import b, c # a will be loaded immediately, though
These imports with not be delayed
from a import * b = __import__(a)
Delayed loading will confuse some third-party modules. In that case you can disable the delay for just that module. For example
There are also versions that can be used with with
with demandimport.enabled(): # do something with demandimport.disabled(): import troublesome.module with demandimport.ignored('test'): import other.troublemaker

pip install demandimport
