print(element)
for num in numbers:
if num >= 0:
print(num, end = " ")
count = 0
for i in numbers:
count += i
avg = count/len(numbers)
print("sum = ", count)
print("average = ", avg)
for num in numbers:
if num % 2 != 0:

This is known as the Metcalfe's Law
Explanation:
In 1980, Metcalfe's law was first presented, not considering users but the communication among compatible devices (e.g. telephone, fax machines and so on). It was after the globalization of the internet that the law got introduced to users and networks.
A demonstration of the law can be seen in fax machines, one fax machine is purposeless, however, the interconnection of multiple fax machines on the network increases the value of every fax machine because the number of the users of the fax machines increases. Similarly, the more the users of a particular service, the more relevant the service becomes.
