Answer:
Following are the code to this question:
file= open('book.txt') #open file
li= {} #define an empty list
for lines in file: # use for loop Split file data into words
d= lines.lower().strip(' !?').split() #define variable d that Add it to map
for val in d: #define loop to store data
if val not in li: #check value is not in list
li[val] = 0 #define list and assign value in 0
li[val] = li[val] + 1 #Sort the book data and add its value
m = sorted(li.items(),key = lambda x : -x[1]) #sorted value into the m variable
print(m[:10]) #print value
Output:

Explanation:
In the given python code first, we open the file "book.txt", in next line, an empty list is defined, that uses the for loop which can be described as follows:
- In the for loop is used, that reads the file data, and defines a variable "d", that stores the values into the map.
-
In the next line another loop is used, that check file values, if values are the same type so, it adds values and writes it.
- In the last line, m variable is used, that sorts the values and use the slicing to print its value.

The correct answer is: Summary
<span>If you only selected fields from a single table in the first screen, then when you click the “Next >” button to continue, you will only need to provide the query with a name and then click the “Finish” button to finish creating the query. If, however, you picked data fields from two or more related tables, then when you click the “Next >” button, you will instead view a second screen which asks if you would like a “Detail” or “Summary” query. You can select the option button for the type of query that you wish to create. If you select “Summary,” then you will be able to click the “Summary Options…” button to open the “Summary Options” dialog box. In this dialog box, you can select what type of summary to perform over a selected field. Make your selections, and then click the “OK” button to return to the “Simple Query Wizard.”</span>
