- 5. select_lines_from_file In this function, we will open a file for reading, look at each line in the file, and return a list of the lines in the file that contain a specified query string. We do not need to change the lines in the file in any way, just put them in a list and return that list. Don't worry about case -- this function is case-insensitive. If we have the following text in a file called final_sample.txt: it was the best of times ce it was the worst of times time keeps on slippin into the future this sentence does not contain that particular word also this one doesn't contain it either Then a sample call should look like: >>> select_lines from file("final sample.txt", "time") ['it was the best of times\n', 'it was the worst of times\n', 'time keeps on slippin into the future\n']### QUESTION FIVE ### def select_lines_from_file(filename, query): pass5. select_lines_from_file In this function, we will open a file for reading, look at each line in the file, and return a list of the lines in the file that contain a specified query string.

- Phyton: 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)…Python Programming Assignment: Create a dictionary that takes a basketball team's information (that includes team's name and points) as parameter, creates a teams_dict and returns it. Also, create a parameter for write_file parameter that opens current results text file in write mode and writes the dictionary information to file as per format and closes the file.IN C++ Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Hints: Use the find() function to find the index of a comma in each…
- In Java Oleae nust read a file A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg GrandCanyon1996_photo.jpg IndianaDunes1987_photo.jpg LakeClark2009_photo.jpg…Please help me write the following function (please see the attached photos for context of the problem): find_treasure(start_map_num): Takes an integer between 0 and 9 as input. Loads the corresponding map file, and starts following the trail (at position 0, 0 of that file) as described above. Continues following the trail through other map files as needed. Places an 'X' at the conclusion of the trail and saves the updated treasure map to a new file with 'new_' prepended to the current map filename. Returns a tuple of the row and column index where the 'X' was placed in that file.def delete_item(...): """ param: info_list - a list from which to remove an item param: idx (str) - a string that is expected to contain an integer index of an item in the in_list param: start_idx (int) - an expected starting value for idx (default is 0); gets subtracted from idx for 0-based indexing The function first checks if info_list is empty. The function then calls is_valid_index() to verify that the provided index idx is a valid positive index that can access an element from info_list. On success, the function saves the item from info_list and returns it after it is deleted from info_list. returns: If info_list is empty, return 0. If is_valid_index() returns False, return -1. Otherwise, on success, the function returns the element that was just removed from info_list. Helper functions: - is_valid_index() """
- This assignment requires you to create a dictionary by reading the text file. Text file name: LightningP Text file contents: Stamkos3538Maroon2933Point5055Kucherov5565Killorn3340 The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. Printing the stats for each player is the most challenging part of this program. The required output should be the same well-formatted table as below: PLAYER COLUMN: 10 characters wide and left-aligned. GOALS COLUMN: 6 characters wide and centered. ASSISTS COLUMN: 8 characters wide and centered. TOTAL COLUMN: 6 characters wide and centered. Example output:write two functions: load_treasure_map(filename): Takes a string as input corresponding to a filename. Opens the treasure map at that filename and loads the treasure map into a list of lists, then returns said list of lists. You can assume that the file will exist. Note that the treasure map could have any number of rows and columns write_treasure_map(treasure_map, filename): Takes as inputs a list of lists corresponding to a treasure map and a string corresponding to a filename. Writes the treasure map to a file at the given filename, with a newline after each row of the map. Does not return anything.Directions: Use a file city.txt for answering the questions that follow each scheduling algorithm.

Parallel Programming It is vaccine season! COVID19 vaccines are out, and everyone is rushing to get one. Vaccines are available from six different brands and you have been entrusted to write a program to count the total number of vaccines of each brand administered across 21 cities in the state. Write a multithreaded program (in the file vaccines.cpp) that counts the number of vaccines in 21 different files of numbers. Each line in each of the files will contain either one of the following brand names: v1, v2, v3. Your program must count the number of units for each vaccine brand administered, across all 21 cities, and display the total number of units for each brand. The files are named…
