You can use __import__, and extend it to handle packages:
try:
reload
except NameError:
from imp import reload # 3.x
def rerun(clsPath, *args):
modPath, clsName = clsPath.rsplit('.', 1)
mod = __import__(modPath, fromlist='not empty')
reload(mod)
cls = getattr(mod, clsName)
return cls(*args)
The fromlist option only cares whether or not the sequence is empty.
If it's not empty you get the leaf (e.g. 'xml.etree.ElementTree' =>
ElementTree). If it's empty you get the base package (e.g.
'xml.etree.ElementTree' => xml).
