Not on import, but you can do this:
import my_module
my_module.set_environment("math") # or cmath, or numeric, or whatever
Your my_module will be like this:
# Warning: untested code.
ENVIRON = None # global variables sometimes have their uses
def f(x):
if ENVIRON is None:
raise ValueError("Uninitialised module!")
# or use a custom exception
return ENVIRON.sqrt(x)
def set_environment(name):
global ENVIRON
ENVIRON = __import__(name)
Does this help?
