Create a program that reads three lines from a text file. Each line should be read one at a time. For each word on a line, the user should be asked to specify how many syllables are in that word. The program should then inform the user if the file contains a valid Hiku using the function below: def isHiku (firstLine, secondLine, thirdLine):if (firstLine == 5 and secondLine == 7 and thirdLine == 5): return True return False print("The file contains a Hiku:", isHiku(5,7,5))Note: You must replace the values in the function with the numbers counted by your program.
PYTHON!!!!! A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies. Below is an example file along with the program input and output: example.txt I AM SAM I AM SAM SAM I AM Enter the input file name: example.txt AM 3 I 3 SAM 3 The program should handle input files of varying length (lines). Program produces correct output given input, test 1 Test Case: Test program with example.txt Input: example.txt Results: AM 3 I 3 SAM 3 Program produces correct output given input, test 2 Test Case: Test program with test file 2 Input: test.txt Results: 3/4 1 98 1 AND 2 GUARANTEED 1 INDEED 1 PERCENT 1 SUCCEED 1 WILL 2 YES 1 YOU 2
Exercise 4: Write a Python program that reads each line ofan input file temperatures.txt that consists of a town name followed by a set of temperatures. The program will then calculate the maximum, minimum, and average temperature and save them in a file called tempSummary.txt. For example, if the temperatures.txt contains Muscat 25 35 30 40 30 Suhar 20 30 25 25 Salalah 35 45 40 15 16 18 The file tempSummary.txt will contain Muscat: 25, 40, 32.00 Suhar: 20, 30, 25.00 Salalah: 15, 45, 28.17
Create a program that calculates the average test scores. Given the student’s name and five test scores, calculate the test scores. The student’s name, five test scores and the average test score is stored in the file testaverage.txt. The data is input from the file test.txt. Sample Run Input file (Contents of the file test.txt) Andrew Miller 87.50 89 65.75 37 98.5 Output file (Contents of the testaverage.txt) Student Name: Andrew Miller Test Scores: 87.50 89.00 65.75 37.00 98.50 Average test score: 75.75
1. Write a program that reads student scores from a file and then writes the scores with a corresponding grade to another file. Assume integer scores whose valid range is 0–100. An invalid score will be given the grade X. Use a function to assign a grade based off the grading scale below. 90 – 100% A 80 – 89% 70 – 79% B C 60 – 69% D 0- 59% F a. Create a file named scores.txt. Place in the same folder as your C program. Fill it with the values below. 95 30 65 500 b. Ifa wrong input file name is entered, an error message should be displayed, and your program should stop with no output file created. c. Ifa correct input file name is entered, the program should ask you for the name of the output file and then fill it with the right values as shown in sample output 2. Once done, it should display a message in the main program letting the user know that data has been saved to the output file. Please note that the values in green in sample output 2 would be the contents of the output file…

Assume that you have two files given : answer.txt and key.txt files. answer.txt file includes student number (int) and the answers of the student. key.txt file includes the answer key for 100 questions. Write a complete C program that reads the exam answers of the student from the file answer.txt, and then compare these answers with the correct answers in key.txt. Finally display the number of correct answers for the student.
Exercise 4: Write a python program that reads from a text file whose name is provided by the user, a list of a coffee shop products ordered by a customer (a sample input file is shown below). Each line contains item name, quantity and price (in biza) per product. Compute and display the total payment amount (in riyals) for each product as well as the total bill. Your program should consider the following erroneous cases: • The file does not open/exist • The format of the data in the file is incorrect (e.g. quantity = "!" or price "8&0"), in which case RuntimeError exception should be raised and the processing stops. Note: Make sure you close any open file even if an error occurs. Enter filename: order1.txt Product Qty Payment Expresso:2 1200 Turkish coffee:3 1250 2.40 3.75 Expresso Turkish coffee File contents invalid. invalid literal for int() with base 10: '880' Shish tawook:2 8&0 Coca cola:! 1300 3 Water 1/2L: 100 Total: 6.15 Sample input file Sample output

Question 3: Write a program that reads a file of text and displays the number of words in that file. The filename is entered by the user. A Word is defined to be any number of consecutive letters (a...z, A...Z) only. Words are separated from each other by spaces (* “) and/or commas (*,') and/or semicolon (*;') and/or full stop (':'). Your program should write the words in the file "output.txt" along with the total word count. As shown below. file.txt Abedef, ;; gfdyire hsdhfkdsf, , ; , dkjfkjdljkfldj. .. mnbsdT .. ;; nbmxhs , a djks. output.txt Abcdef gfdyire hsdhfkdsf dkjfkjdljkfldj mnbsdT nbmxhs a djks Total count of words are = 8
