- The function last_words in python takes one parameter, fname, the name of a text file, and returns a list containing the last word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["red", "yellow", "green"] should be returned. NOTE: You may assume the file will contain no blank lines. BIG HINT: If line is a string representing a line of text (inside a for loop!), then L = line.split() creates a list of the words in the line. For example: Test Result L = last_words("wordlist1.txt") print(L) ['happy', 'sad', 'angsty', 'euphoric', 'maudlin']*Code in python Write a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number. An example file and the program input and output is shown below: example.txt Line 1.Line 2.Line 3. Enter the input file name: example.txt The file has 3 lines. Enter a line number [0 to quit]: 2 2 : Line 2. The file has 3 lines. Enter a line number [0 to quit]: 4 ERROR: line number must be less than 3. The file has 3 lines. Enter a line number [0 to quit]: 0 Make sure the program gracefully handles a user entering a line number that is too high.Program Description: The project is a student management system which maintains student records in a simple text file. Your task is to write a program to save a list of students records in a FILE and then perform several operations on this FILE. Your program will ask user to choose the option from a menu. The 3 major function in menu are: ADD STUDENT FIND STUDENT PRINT LIST Exit How it Works The menu is handled by do while and switch statement. Sample output The Methods to be implemented are as follows: 1. ADDSTUDENT This method will add a new student to the file. It takes 3 parameters ( student name, id, and GPA). Your program must ask the user to enter the details of new students: Name, ID and GPA 2. FINDSTUDENT This method will search for a student with his/her id in the file. If the student is found it will print her/his record to the output. If the student is not found it will print “There is no record of this student in this system” 3. PRINTLIST This method will print all the…
- phyton Topics: list and list processing You will write a program to read grade data from a text file, displays the grades as a 5-column table, and then print the statistics (min, max, median, and median). You can assume that the input file only one number per line. You can assume the user always enter a file that exists. The median is the value in the middle of a sorted list. To sort a list, use list.sort() function. It’s computed as below. For a list of odd length, the middle number is just the length divide by 2. For the list, [1,2,3], the median is 2 since 2 is in the middle of the list. The middle index is 3//2, which is 1. Remember that // is the integer division operator. When the length of the list is even, there are two middle numbers. The median is the average of the two middle numbers. For example, [1,2,3,4], the median is (2+3)/2 = 2.5. The two middle indexes for this example are (4//2)-1 = 1 and (4//2) = 2. Functions you need to write: read_grades() Prompts…scores.txt : Jan,86 Drew,92 Blake,85 Alex,81 Taylor,88 Jordan ,72Cam,89 Note: code is written in python using strings and lists only The file scores.txt (attached) contains a list of names and test scores. Create a program that reads each line of the file and determines the highest score and who obtained it. This is an exercise in strings. You are required to use at least one string method to determine the names and the scores. Your output should resemble the following: Highest Score: 100Achieved by: Jay Note; i could not send an attachment of the actual file but i have copied its contents.Programming Challenge #7: Word Frequency Count: Write a program that allows the user to specify a text file, opens the file, and prints a two-column table consisting of all the words in the file together with the number of times that each word appears. Words are space-delimited and case-sensitive. The table should list the words in alphabetical order.
- The python function first_words takes one parameter, fname, the name of a text file, and returns a list containing the first word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["apples", "bananas", "limes"] should be returned.NOTE: You may assume the file will contain no blank lines.BIG HINT: If line is a string representing a line of text (inside of a for loop!), then L = line.split() creates a list of the words in the line.C++ Programming. Associative and unordered associative containers. Associative containers (set, map, multiset, multimap). • When executing a given task, the input values must be read from a text file. Task : Create a program that deletes a set of elements from a single word of a given string type and creates a second set of elements that consist of a single word, and also displays it on the screen.5. Charge Account Validation If you have downloaded the source code from the Computer Science Portal you will find a file named charge_accounts.txt in the Chapter 07 folder. This file has a list of a com- pany's valid charge account numbers. Each account number is a seven-digit number, such as 5658845. Programming Exercises 403 program Write a program that reads the contents of the file into a list. The program should then ask the user to enter a charge account number. The program should determine whether the number is valid by searching for it in the list. If the number is in the list, the should display a message indicating the number is valid. If the number is not in the list, the program should display a message indicating the number is invalid. (You can access the
- JAVA INTRO Create a program that generates a report that displays a list of students, classes they are enrolled in and the professor who teaches the class. There are 3 files that provide the input data: 1.

The first line in the file contains the population for 1950, the second line contains the population for 1951, and so forth. Write a program that reads the file's contents into a list. The program should display the following data: the average annual growth in population during the time period the year with the greatest increase in population during the time period (highest growth rate) the year with the smallest increase in population during the time period (smallest growth rate) 151868 153982 156393 158956 161884 165069 168088 171187 174149 177135 179979 182992 185771 188483 191141 193526 195576 197457 199399 201385 203984 206827 209284 211357 213342 215465 217563 219760 222095 224567 227225 229466 231664 233792 235825 237924 240133 242289 244499 246819 249623Phyton: Program 6: Write a program that allows the user to add data from files or by hand. The user may add more data whenever they want. The print also allows the user to display the data and to print the statistics. The data is store in a list. It’s easier if you make the list global so that other functions can access it. You should have the following functions: · add_from_file() – prompts the user for a file and add the data from it. · add_by_hand() – prompts the user to enter data until user type a negative number. · print_stats() – print the stats (min, max, mean, sum). You may use the built-in functions. Handling errors such as whether the input file exist is extra credit. To print a 10-column table, you can use the code below: for i in range(len(data)): print(f"{data[i]:3}", end="") if (i+1)%10==0: print() print() Sample run: Choose an action 1) add data from a file 2) add data by hand 3) print stats 4)…
