Question

Write a function secondLst() that takes a two-dimensional list as a parameter and returns a new list containing all of the integers found in the list. The list can contain any type of item. The type() function can determine what type of object is currently stored in a variable and is helpful for this question. If the list is empty or the list contains no integers, the function should return the empty list. The function will ignore integers found in other types (e.g. dictionaries, tuples, etc.). The function should not change the list passed as a parameter in any way.

This is the output in python please.

Explanation / Answer

def buildList(lst1):

    arr = []

   

    # read one row at a time

    for x in lst1:

   

        # read one element of current row at a time

        for y in x:

       

            # if y is of type int

            if type(y) == type(1):

                #print('hi')

                arr.append(y)

               

    return arr

   

lst1 = [ ['test' , 1], [ 'two', 2, 3.5 ], [(1.2, 5) , 3.14] ]

print(buildList(lst1))

lst2 = [ ['one'], ['two'], [True], ['three'], [{1:2}], ['four'] ]

print(buildList(lst2))

Sample Output

[ 1 , 2 ]
