Question

1. what will be displayed by the following program? values = 7, 4, 5, 3, 8, 6, 1, 2 v = values00 for lst in values: for element in lst: if v > element: v = element print(v) 1 8 3 7 6 7. assume m = 1, 2, 3, 4, 5, 6. what does len(m) output? 2 4 3 0 1

Explanation:

Step1: Analyze first program

The program initializes a 2 - D list values. v is first set to values[0][0] which is 7. Then, it iterates through all elements in the 2 - D list. If an element is less than v, v is updated to that element.

Step2: Find minimum element

The minimum element in the list [[7, 4, 5, 3], [8, 6, 1, 2]] is 1. So, the program will print 1.

Step3: Analyze second program

The len() function in Python returns the number of elements in an object. For a list, if it is a 2 - D list like m = [[1, 2, 3], [4, 5, 6]], len(m) returns the number of sub - lists, which is 2.
