|
True |
True/False: Invalid indexes do not cause slicing expressions to raise an exception |
|
True |
True/False: Lists are dynamic data structures such that items may be added to them or removed from them. |
|
False |
True/False: Arrays, which most other programming languages allow, have much more capabilities than list structures. |
|
False |
True/False: A list cannot be passed as an argument to a function |
|
False |
True/False: The remove method removes all occurrences of the item from a list |
|
False |
True/False: The sort method rearranges the elements of a list so they appear in ascending or descending order. |
|
True |
True/False: The first step in calculating the average of the values in a list is to get the total of the values. |
|
False |
True/False: Indexing starts at 1, so the index of the first element is 1, the index of the second element is 2, and so forth. |
|
True |
True/False: The index – 1 identifies the last element in a list |
|
True |
True/False: In slicing, if the end index specifies a position beyond the end of the list, Python will use the length of the list instead. |
