Why would you do that?

You may be able to avoid the ImportError by moving the instance from the 
global scope into a function, e. g. instead of

e = Excel()
# work with e

do

def main():
    e = Excel()
    # work with e
main()

but the more appropriate answer is likely: Don't use __del__() at all.
