Question

def comp (n, pred): "" Uses a one line list comprehension to return list of the first n integers (0...n-1) which satisfy the predicate pred. >>> comp (7, lambda x: x%2 ==0) [0, 2, 4, 6] "*** YOUR CODE HERE ***"

Can you also explain the functions and what they do please? Thanks!

Answer 1

def comp(n, pred):
    # Initializing result list with empty list
    result = []

    # loop through values from 0 to n-1
    for i in range(n):
        # Checking i is satisfied for pred
        if(pred(i)):
            # If not satisfied then adding it to result list
            result.append(i)

    # Returning result
    return result


# Testing
print(comp(7, lambda x:x%2==0))
