A perfect number is defined as a number whose proper divisors, i.e., not including the number itself, add up to the number.

def isPerfect(n): """ Returns True or False depending on whether the argument is a perfect number. """ return sum(divisors(n)[:-1]) == n # divisors is defined in the previous question.

Consider the following functions, which together produce a list of perfect numbers.

def havePInRange(low, high, p): """ Returns a list of the numbers in range(low, high+1) that have property p. For example, suppose we define def isOdd(x): return x % 2 == 1 then: havePInRange(91, 97, isOdd) => [91, 93, 95, 97] """ return

def perfectInRange(low, high): """ Returns a list of the perfect numbers in the range(low, high+1). For example: print(perfectInRange(1, 1000)) => [6, 28, 496] """ return

Complete the definitions of havePInRange and perfectInRange.
