randomlist = []

for i in range(0,20):

An empty list called randomliay is created to hold the generated random integers.

Using a for loop, we specify the range of random numbers we want.

Inside the for loop ; we attach our generated random integer which will be in the range (-29 to 30) in a variable n

For each n value generated, if the value is less than 0( it is negative, since all the values are integers), replace the value with 100.
