Define a function named sum_values with two parameters. The first parameter will be a list of dictionaries (the data). The secon

d parameter will be a string (a key). Return the sum of the dictionaries' values associated with the second parameter. You SHOULD NOT assume that all of the dictionaries in the first parameter will have the second parameter as a key. If none of the dictionaries have the second parameter as a key, your function should return 0. Sample function call: sum_values(data, 'estimated_annual_kwh_savings') sum_values_by_year

sum = 0

def sum_of_values(dict_data, number_of_boys):

for dict in dict_data:

for key in dict.keys():

if key == number_of_boys:

sum += dict[key]

//After looping check the sum variable and //return the appropriate value.

if sum != 0:

return sum

elif sum == 0:

//There was no key of such so no addition.

Cell address A4 in a formula means it is a _________Mixed cell reference​
wel

Answer:

Relative cell reference.

Explanation:

Microsoft Excel is a software application or program designed and developed by Microsoft Inc., for analyzing and visualizing spreadsheet documents.

A spreadsheet can be defined as a file or document which comprises of cells in a tabulated format (rows and columns) typically used for formatting, arranging, analyzing, storing, calculating and sorting data on computer systems.

A relative cell reference can be defined as a cell whose reference is mainly relative to the location of the cell.

In Microsoft Excel, the cell reference is considered to be a relative reference by default.

Hence, the cell address A4 in a formula means it is a relative cell reference and when the formula is copied, the reference in the formula will change.

For example, if you refer to cell A4 from cell D4, it means you're pointing to the cell that is three (3) columns to the left of the same row i.e D minus A (D - 4).

Given the lists list1 and list2 that are of the same length, create a new list consisting of the last element of list1 followed
Inessa [10]

Answer:

list1 = [1, 2, 3]

list2 = [4, 5, 6]

list3 = []

newlist = []

for i in list1:

   for j in list2:

       if list1.index(i) == list2.index(j):

           newlist.append(j)

           newlist.append(i)

           break

   

for i in reversed(newlist):

   list3.append(i)

print(list3)

Explanation:

The programming language used is python.

List 1 and 2 are initialized, and two empty lists are initialized too, these two lists are going to be used in generating the new list.

Two FOR loops are used for both list one and two respectively, to iterate through their content, the IF statement and the break is placed within the for loop to ensure that there is no repetition.

The index of list 1 and list 2 are appended (added) to a new list one at a time.

The new list is then reversed and its content are added to list 3 to give the final solution.

NOTE: The reason a separate list was created was because the reversed() function does not return a list, so in order to get the list, it must be added to an empty list as you reverse it.
