Q2: Suppose that the file (employee.txt) shown in the figure was stored in the default path, the data stored in this file is employee's name (string), his age (integer), and his salary (double); this data is stored for unknown number of employee.

please code in pythonredact_file: This function takes a string filename. It writes a new file that has the same contentsas the argument, except that all of the phone numbers are redacted. Assume that the filename has onlyone period in it. The new filename is the same as the original with '_redacted' added before theperiod. For instance, if the input filename were 'myfile.txt', the output filename would be'myfile_redacted.txt'. Make sure you close your output file.The first hard task in this function is to make the output filename from the input filename that waspassed in. You can break it into two pieces by splitting on the dot or by using the index method andslicing. Then put it back together again using string concatenation.We are also working with files in this one. To open a file with a filename stored in the variable fname,in read mode use the open function as such: fp = open(fname). You will need to open the outputfile in write mode: open(fname, 'w'). Then you can traverse the…

2. Message Decoder Create a MessageDecoder program that reads from a file (one character at a time), and writes all non-numeric characters to a file called DecodedMessage.txt, displaying a secret (and motivational) message. ***Hint: .read() will return an int, but this can be type cast as a char. int and char are interchangeable (via type-caşting). You could run a loop on a condition like charInFile != (char) -1 Don't forget that -1 is a special character that denotes the end of a file!
Exercise 2 (30/40): Write a program that reads in a set of coin descriptions from a file. The input file has the format coinNamel value is coin Valuel coinName2 value is coinValue2 Add a method to your program that receives file content and writes back to another file statistics about the coins. Sample input file Riyal value is 25 Baisa value is 6.0 BHR value is baisa value is 5.30 Riyal value is 23.5 Sample output file Riyal = 24.25 Baisa =5.65 BHR = 9.5 In the solution 1. use the coin class provided on Moodle. 3.

WriteaC++programthatpromptstheusertoenterafilenamethatcontains the total mark of students. Each line in the input file contains a student name followed by the student’s total mark. The program should ask the user for the passing threshold (i.e. student whose total mark is greater than or equal the threshold will pass the course) and copy the students who pass the course to a new file (the name of the output file is specified by the user). Moreover, the output file should be format so that all the marks are displayed with two digits after the decimal point. The width for the names and marks fields should be eight and seven, respectively. A sample input and output files are shown below (the passing mark in this sample is assumed to be 60).

1. Write a program that opens an output file with the filename my_name.txt, writes your name to the file, then closes the file. 2. Write a program that opens the my_name.txt file that was created by the program in problem 1, reads your name from the file, displays the name on the screen, then closes the file. Write code that does the following: opens an output file with the filename number_list.
Given a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program should first read the name of the text file from the user. The program then should read the text file, line by line. If a food is available, the program should output the available food item in the following format: name (category) -- description Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character ('\t'). Hints: Use the find() function to find the index of a tab character in each row of the text file. Use the substr() function to extract the text separated by the tab characters. Ex: If the input of the program is: food.txt and the contents of food.txt are: Sandwiches Ham sandwich Classic ham sandwich Available Sandwiches Chicken salad sandwich Chicken salad sandwich Not available Sandwiches Cheeseburger Classic cheeseburger Not…
A file contains a list of telephone number in following form. Aman 23456 Raj 567854 ….. ………. Assume 10 such entries. Name contains only one word and name and telephone number are separated by 5 white spaces. -->Write a program that will create the data file containing the list of telephone number given in above form. Use a class object to store each set of data.
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
****IN PYTHON! Write a function named file_stats that takes one string parameter (in_file) that is the name of an existing text file. The function file_stats should calculate three statistics about in_file: the number of lines it contains, the number of words and the number of characters, and print the three statistics on separate lines. For example, the following would be the correct input and output:>>> file_stats('created_equal.txt')lines 2words 13characters 72Note: The number of characters may vary slightly between operating systems. Similarly, the number of lines may vary by 1 line, depending on the method used to calculate it. I attached a picture of my code so far and a picture of what the text file reads.
