      new_list = my_list[i]
  print('{} {}: {} {}'.format(new_list[0], new_list[1], new_list[2], new_list[3]))

• 
  for i, j in enumerate(my_list):
      for item in my_list[i]:
          new_list.append(item)
  print('{} {}: {} {}'.format(new_list[0], new_list[1], new_list[2], new_list[3]))

What is output?

new_list = [['hello', 'word'], 'good morning', 'have a nice day'] print(new_list[0:2])

• ['hello', 'word']

• [['hello', 'word'], 'good morning']

• ['hello', 'word', 'good morning']
