You can try to simplify that a bit: - Handle the case with non-negative exponents in one branch - Avoid duplicating the for loop for negative exponents, e. g. by calling power() from within power() Once you have that working you can play around a bit, e. g. - try an alternative implementation using recursion instead of a loop - modify the code to minimize the number of multiplications it needs to perform to get the result _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
