Answer:
Python file with appropriate comments given below
Explanation:
#Take the input file name
filename=input('Enter the input file name: ')
#Open the input file
inputFile = open(filename,"r+")
#Define the dictionary.
list={}
#Read and split the file using for loop
for word in inputFile.read().split():
#Check the word to be or not in file.
if word not in list:
list[word] = 1
#increment by 1
else:
list[word] += 1
#Close the file.
inputFile.close();
#print a line
print();
#The word are sorted as per their ASCII value.
fori in sorted(list):
#print the unique words and their
#frequencies in alphabetical order.
print("{0} {1} ".format(i, list[i]));
Answer:
e) Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".
Explanation:
<em>if - elseif - else statements work in sequence in which they are written. </em>
- <em> </em>In case <em>if() statement is true, </em>else if() and else statements will not get executed.
- In case <em>else if() statement is true</em>, conditions in if() and else if() will be checked and else statement will not be executed.
- In case <em>if() and else if() both are false</em>, else statement will be executed<em>.</em>
First, let us consider code segment I.
In this, first of all "pea" is checked in if() statement which will look for "pea" only in the String str. So, even if "pearl" or "pear" or "pea" is present in 'str' the result will be true and "pea" will get printed always.
After that there are else if() and else statements which will not get executed because if() statement was already true. As a result else if() and else statements will be skipped.
Now, let us consider code segment II.
In this, "pearl" is checked in if() condition, so it will result in desired output.
Executable code is attached hereby.
Correct option is (e).

Answer:
Here is the Python program which has a function sum_scores:
def sum_scores(score1, score2, score3, score4):
sum = score1 + score2 + score3 + score4
print(sum)
sum_scores(14,7,3,0)
Explanation:
- Method sum_scores takes four arguments, score1, score2, score3, score4.
- The sum variable adds these four scores and stores the value of their addition.
- Lastly print statement is used to print the value stored in sum variable which is the value obtained by adding the four scores.
- Last statement calls the sum_scores method and passes four values to it which are 14,7,3,0
- The output of the above program is:
- 24
- If you want to use return statement instead of print statement you can replace print(sum) with return sum. But in order to display the sum of the scores you can replace sum_scores(14,7,3,0) with print(sum_scores(14,7,3,0))
- The program along with the output is attached as a screenshot.
Answer: Business intelligence
Explanation:
Most of the enterprises and organizations collects huge amount of data through the use of MIS. These data can be based on any aspect of the business. But the collection of such large sets of data is useless until and unless there is a business intelligence associated with it. the work of business intelligence is to use software tools for analysis of the collected data so that it could be useful for enterprise or company to look for patterns and trends in the market.
The outcome of such business intelligence is very helpful particularly to managers, executives for taking particular decisions in the greater interest of the company.
So we can say, business intelligence is an approach to boundary spanning that results from using sophisticated software to search through large amounts of internal and external data to spot patterns, trends, and relationships that might be significant.
