When using Python 3 lists {fill in the blank}.

A. ! a negative lookup (such as `somelist[-3]`) refers to list values positioned relative to the end of the list
B. a copy of the list contents is made as the result of a statement such as `some_other_list = somelist`
C. ! we can refer to the list from the second element to the end using `somelist[1:]`
D. Python 3 ensures all values within the same list have the same type
E. None of the above.

Answer 1

Answer:D

A. ! a negative lookup (such as `somelist[-3]`) refers to list values positioned relative to the end of the list - True Explanation: list1=[1,2,3] print(list1[-1]) is acutally going to print 3 which is the last element of the list. using a negative look up we are accessing the list from rare
B. a copy of the list contents is made as the result of a statement such as `some_other_list = somelist` - True copying contents of a list to another list in python is easy one=[1,2,3] two=one is just going to copy the list
C. ! we can refer to the list from the second element to the end using `somelist[1:]`- True That is the correct syntax in python
D. Python 3 ensures all values within the same list have the same type -False list1=[1,'b',3.3,'samantha'] this list is valid in python print(list1[1]) and this line is going to print b to the terminal
E. None of the above.
