Question

PYTHON 3. Write code using zip and filter so that these lists (l1 and l2) are combined into one big list and assigned to the variable opposites if they are both longer than 3 characters each.

l1 = ['left', 'up', 'front']
l2 = ['right', 'down', 'back']

Answer 1

11,12 = ['left', 'up', 'front'],['right', 'down', 'back') #Listl and List2 are defined here bigger list = zip(li, 12) #This function combines both the list into a list of tuples #of two values with one value from li and other from 12 filtered list = filter(lambda pair:len (pair[0])>3 and len (pair[1]) >3 ,bigger list) #this creates (object of filtered list) #and lambda is used instead of function to #make it simple one line code, same thing can #be done via function as well. #pair defines tuple and then we add a condition #that if element at index and 1 has length #greater than 3, then accept it. opposites=list(filtered_list) #object is converted into list to see the elements inside it. #print (opposites #uncomment to see the filtered objects.
