[16]A __________ function is a nameless function defined without using “def" which can be assigned and referenced as a variable.
(a)concurrent (b)lambda (c)assert (d)global
A. b
[17]The __________ built-in function takes in a function and a list, applies the function to every element of the list, and returns a list containing the results.
(a)reversed() (b)filter() (c)map() (d)reduce()
A. c
[18]The __________ built-in function takes in a function which returns True or False, and a list. It applies the function to every element of the list. Then, it returns a new list containing every element for which the function had return True.
(a)map() (b)reduced() (c)filter() (d)reversed()
A. c
[19]The __________ built-in function takes in a function and a list. For each item in the list, it executes the function taking in the list, it executes the function taking in the item and the next item, and only returning one value. In this way, it aggregates all values in the list into one value.
(a)reduce() (b)reversed() (c)filter() (d)map()
A. d
[20]The __________ built-in function takes in a list and returns a new list with the elements backwards order.
(a)reserved() (b)reduce() (c)map() (d)filter()
A. a
[21]Given the following Python code:
x = 10 if True else 5
What is the value of x?
(a)10 (b)None (c)5 (d)Syntax error thrown
A. a
[22]Given the following Python code:
x = 10 if False else 5
What is the value of x?
