At the end of this and other textbooks, there usually is an index that lists the pages where a certain word appears. In this problem, you will create an index for a text but, instead of page number, you will use the line numbers.
You will implement function index() that takes as input the name of a text file and a list of words. For every word in the list, your function will find the lines in the text file where the word occurs and print the corresponding line numbers (where the numbering starts at 1). You should open and read the file only once
Create the python function as part of a python program. The data required for the function should be created in the python program and passed to the function.
its an exercise pyrthon problem 6.27
I opened a CSV file in C++ and the headings of the file are Name, Class, Subject, Standing (in same order).
I want to output the file on the console in ascending order of Subject (later I will be performing insert sort). how do I make it in ascending order of Subject which is third column. please add code.
Write a program that reads words from a file (filename given as a string parameter) and prints the occurance of each word(case insensitive). And print the words in alphabetical order.
For example, if the file contains text
Love is free free is love
then the function should print
free:2 is:2 love:2
def count_word(filename):
# YOUR CODE HERE raise NotImplementedError()

- This needs to be written in C programming. It is a practice program and it is not graded. So if you could help that would be great. I just need someone to show me what the program looks like.arrow_forwardpls code in pythonplagiarism: This Boolean function takes two filenames. If any line occurs in both files, return True.If not, return False. I suggest using nested loops. With nested loops, we call the loop that is in thebody of the other loop, the "inner loop". The loop that contains the inner loop is the "outer loop". Openthe second file inside the outer loop:for line1 in file1:file2 = open(fname2)for line2 in file2:Python only lets you read the file once per open, so you need this order of instructions. Make sure yourreturn False is outside of both loops. Otherwise, you will only compare the first two lines of thefiles. Make sure you close the file that gets read repeatedly after the inner loop but still inside the outerloop.Here is some (more complete) pseudocode to get you started:open file 1for line1 in file 1open file 2for line2 in file 2:if line1 == line2:return Trueclose file 2return Falsearrow_forwardWrite a program in C++ that creates a file and writes data into that file column wise. The problem is that there is some data that I want to keep there permantely and I do not want to replace it every time. For example this format: TIME DAY MONTH YEAR 01:25 07 JUNE 2008 14:00 30 MARCH 2019 I have (TIME/ DAY/ MOTH/ YEAR) and I want to write that first and that any data that I add later is written under that and so on. If I want to add the row (05:05/ 10/ July/ 2000) following the pattern. Write code that checks if the file has data and write that data under the lines you already have.arrow_forward

You can assume the file only contains thealphabet characters and the space character. However there may be morethan one space character between two words, so “abc abc” and “abc abc”,for example, are both two words. int wordCount ( const char * filename ) {}arrow_forward

The program will get the names from a file. The names should be read in until there is no more data to read. The program should prompt the user for the file name and read the data from the file. A suitable file of names (List of Random Names) is provided on Moodle. Note that these names might include spaces; handle your input accordingly. The expected output is two names; do not show the entire file (or you will regret that code when you do the associated programming quiz that processes thousands of names). Do not use arrays or sorting for this problem.arrow_forwardWrite a function called countWord(). It takes 2 parameters: The name of a text file(e.g. gettysburg.txt) and a word to be searched within that file. Your code should returnthe number of times the given word appears in the file.>>> countWord('gettysburg.txt', 'people')3arrow_forward
- Do not read directly from the example files, as the automated testing system expects you to read from the standard input. Instead, process the lines as follows: 3 - Geography Grades 3 Make a copy of your program for the problem Geography Grades 2 and change the code in such a way that your program can process multiple groups. These groups are on the input separated by ’=\n’. Every group starts with a first line that contains the name of the group and the lines after contain the information about the students in the same way as is specified for the problem Geography Grades 1.
