Answer:
The answer to this question is option "b".
Explanation:
In the method definition, we perform swapping. To perform swapping we define a variable "temp" that swap values of variable p1 and p2 and store in array that is "values". and other options are not correct that can be defined as:
- In option a, It does not insert any new value in array because we do not pass any value in function.
- In option c, The function does not copy and assign a value in a new array because in this function we not assign any new array.
- In option d, It is incorrect because it can not move an element into high index position.
I think the answer to this would be true

Apps do a single function where applications do multiple functions
Answer:
- def getData(a_dict, key_list):
- result = []
-
- for key in key_list:
- result.append(a_dict[key])
-
- return result
-
- result = getData( {"puffin": 5, "corgi": 2, "three": 3} , ["three", "corgi"])
- print(result)
Explanation:
Let's define a function <em>getData() </em>with two parameters,<em> a_dict </em>and <em>key_list</em> as required by the question (Line 1).
Since the function is to return a list of associated values of dictionaries, a new list,<em> result</em>, is declared and initialized with empty values (Line 2).
Next, use for-loop to traverse through every string in the input <em>key_list </em>(Line 4) and use the traversed key to address the value in the<em> a_dict </em>and add it to the <em>result</em> list (Line 5)
At last, return the <em>result </em>list as output (Line 7)
We can test the function using the test case from the question and we shall see the output as follows:
[3, 2]
