- Print Person Information from file In this lab you are asked to complete the function : print_person_from_file(person_name, filename). This function should read in data from the file filename and print the information for person_name if it is found in the file. The file filename contains lines, in comma separated format (with a 'csv' extension) For each line, the items in each field are as follows: Field 1 3 4 Name Place of Birth Date of Birth Children For Children: • a person can have 0, 1 or multiple Children Multiple children are semi-colon separated If a person has no children the field contains 'NA' For example, consider the following lines froma .csv file, where Fletcher_Margaret has 3 children, and Baker_Jill has 0 children (field 4 contains the string 'NA') Fletcher Margaret,Sydney,30-09-1921,Green Bob;Green Nancy;William Tom Baker_Jill, Melbourne,08-09-1973, NA Format for Printing If the person_name is found in the file, the format for printing the person information is as…Python - Next Birthdate In this task, we will write a program that reads birthdate data from a given CSV file, and given the current date, determines which person's birthday will be celebrated next. Create a function with the following signature: nextBirthdate(filename, date) filename: parameter, which represents the CSV filename. date: parameter, which represents the current date. The function should open the CSV file, read the birthdate data, and determine which person's birthday will be celebrated next, given the current date. The name of the person should be returned. In other words, given a date, find the person whose birthday is next. Sample Run birthdates.csv Draven Brock, 01/21/1952 Easton Mclean, 09/02/1954 Destiny Pacheco, 10/10/1958 Ariella Wood, 12/20/1961 Keely Sanders, 08/03/1985 Bryan Sloan,04/06/1986 Shannon Brewer, 05/11/1986 Julianne Farrell,01/29/2000 Makhi Weeks, 03/20/2000 Lucian Fields, 08/02/2018 Function Call nextBirthdate("birthdates.csv", "01/01/2022") Output…Finish this program from the code posted below! Note: There should be two files Main.py and Contact.py You will implement the edit_contact function. In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return. Code:from Contact import Contactimport pickledef load_contacts():""" Unpickle the data on mydata.dat and save it to a dictionaryReturn an empty dictionary if the file doesn't exist """try:with open("mydata.dat", 'rb') as file:return…
- C++ Create a function that will read the following .txt file contents and put them into an array: "apple", "avocado", "apricot","banana", "blackberry", "blueberry", "boysenberry","cherry", "cantaloupe", "cranberry", "coconut", "cucumber", "currant","date", "durian", "dragonfruit","elderberry",File names: color_square.py, chessboard.py, test_squares.py Positions on a chess board are identified by a letter and a number. The letter identifies the column; the number identifies the row. See the image below. You will provide the functions that allow us to determine: if a chessboard square is either black or white, given its coordinates. If the row/column is valid or not for the standard chessboard For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False. Requirements: Your function for validating the column should be able to accept upper or lowercase strings as parameters. Your functions for validating the row should be able to accept integers or strings as parameters. Your function that determines black-or-white may assume that the input has been validated prior to us calling…13. Write function quote() that takes as input the name of a file (as a string) and anindex i (as an integer). The file will contain quotes, one per line. The function shouldopen the file, read the file, close the file, and return the i-th quote (i.e. the i-th line in thefile), assuming that the quote numbering starts at 0. Test your solution onfile Wilde_Quotes.txt.>>> quote("Wilde_Quotes.txt", 5)'At twilight, nature is not without loveliness, thoughperhaps its chief use is to illustrate quotations from thepoets.\n'>>> quote("Wilde_Quotes.txt", 0)'A little sincerity is a dangerous thing, and a great dealof it is absolutely fatal.\n'>>> quote("Wilde_Quotes.txt", 23)'Patriotism is the virtue of the vicious. \n'>>>
- 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…Problem Definition Task. Your task is to develop a python program that reads input from text file and finds if the alphanumeric sequence in each line of the provided input file is valid for Omani car license plate. The rules for valid sequences for car plates in Oman are as follows: Each sequence is composed of 1 to 5 digits followed by one or two letters. Digits cannot start with 0, for instance, 00, 011, or 09 are not valid digit sequences. The following list are the only valid letter combinations: ['A','AA','AB','AD','AR','AM','AW",'AY"', 'B', BA','BB','BD',"BR','BM',"BW',"BY', 'D','DA','DD','DR','DW','DY', 'R','RA','RR','RM','RW','RY', 'S','SS', 'M','MA','MB','MM','MW','MY", "W',"WA',WB',"wW', Y,YA','YB','YD','YR','YW',YY] Program Input/Output.

Create a function that reads the file and items' quantity and price to two different arrays. Create a function that computes the subtotal of each item. Implement all functions inside the main program and the computed value should be displayed with the item's name.Body Mass Index Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula: BMI = weight × 703 / height2 where weight is measured in pounds and height is measured in inches. The file is in the format name weightInKG heightInCM You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch). The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight. Your output should look like A person’s weight…Help me homework c++ The shots file holds a list of shots (imagine some hitscan weapon in a video game like a shotgun or something). Each shot has an origin and a direction. The origin is an (x,y) coordinate, like (5,3). The direction is a slope and whether the shot is traveling along that slope or in the reverse. A slope of "Vertical" means that the shot is travellingstraight up and down. The format is:x_location y_location slope(either a number like 2.1 or a non-number meaning"Vertical") forwards(1 meaning forwards, 0 meaning backwards) 0 0 0 00 0 0 10 0 Vertical 00 0 Squirrel 110 10 -1 1-10.1 -100.01 2.1 0 The first line is a horizontal line shooting left from the origin (0,0).The second line is a shot also travelling horizontally from the origin, but forward along the x axis instead of backwards.The third line is shooting straight down out of the originThe fourth line is shooting straight up out of the origin (any non-number means Vertical, not just Vertical)The fifth line is…
