+# Perfect number: Perfect number is a positive integer that is equal to the sum of its proper divisors.

+# Some other perfect numbers are 28(1+2+4+7+14=28), 496 and 8128.
+# 
+# Write a function that finds perfect numbers between 1 and 1000. Check perfect numbers between 1 and 1000 and find the sum of the perfect numbers using reduce and filter functions.
