3. Laramie Park District has files of participants in its summer and winter programs this year. Each file is in participant ID number order and contains additional fields for first name, last name, age, and class taken (for example, Beginning Swimming). a. Design the logic for a program that merges the files for summer and winter programs to create a list of the first and last names of all participants for the year in ID number order.

Assignment 8. Student -324 234.428, .
Write the function plot_all_time_series (filename) that takes a filename and plots lines showing the TL13 over time for all lakes in the file. Notes: • Your function must set the names for each data plot (using label=...) and display a legend, in the default location (that is, you don't need to specify the legend location - leave it to matplotlib). o Be aware, the label for each line won't be listed if you don't turn on the legend. • The graph title should be generated using the following f-string, f'TLI3 over time for all lakes in (filename}'. • Other than that your graph be just like your single series graph except that it has multiple plots drawn on the same axes. • You should include and call, at least, your float_array and read_raw_data_dict functions. Don't reinvent the wheel! In fact you can include all your code so far :) • No function definition can contain more than 20 lines of code (excluding docstring and comments). Example plot plot_all_time_series('time_series_01.csv')…
Please help write the functions (context for the problem in the images): write_X_to_map(filename, row, col): Takes as inputs a string corresponding to a filename, and two non-negative integers representing a row and column index. Reads in the map at the given filename, inserts an X into the given row and column position, then saves the map to a new file with 'new_' prepended to the given filename. You can assume the filename given to the function as argument refers to a file that exists.
write in c++Write a program that would allow the user to interact with a part of the IMDB movie database. Each movie has a unique ID, name, release date, and user rating. You're given a file containing this information (see movies.txt in "Additional files" section). The first 4 rows of this file correspond to the first movie, then after an empty line 4 rows contain information about the second movie and so forth. Format of these fields: ID is an integer Name is a string that can contain spaces Release date is a string in yyyy/mm/dd format Rating is a fractional number The number of movies is not provided and does not need to be computed. But the file can't contain more than 100 movies. Then, it should offer the user a menu with the following options: Display movies sorted by id Display movies sorted by release date, then rating Lookup a release date given a name Lookup a movie by id Quit the Program The program should perform the selected operation and then re-display the menu.

PROBLEM 2: Save your file as Surname_Pandas-P2.py Using the dataframe cars in problem 1, extract the following information using subsetting, slicing and indexing operations. a. Display the first five rows with odd-numbered columns (columns 1, 3, 5, 7...) of cars. b. Display the row that contains the 'Model' of 'Mazda RX4'. C. How many cylinders ('cyl') does the car model 'Camaro Z28' have? d. Determine how many cylinders ('cyl') and what gear type ('gear') do the car models 'Mazda RX4 Wag', 'Ford Pantera L' and 'Honda Civic' have.
Complete the below function that takes a file name and a list as arguments andreads the text within the corresponding file, then creates a dictionary whosekeys are the characters of the provided list, and the values are the counts ofthese characters within the text. If a character in the list is not included in the text, "0" should be written in the dictionary as the value of this character. The function returns the created dictionary as a result. If the file does not exist, then the function returns an empty dictionary. Here is an example case, assuming a file named "sample.txt" exists with the following content: ----- sample.txt -----This is an example sentence.This is yet another sentence.------------------------- >>> text2dict("sample.txt", ['a', 'b', 'c', 't']){'a':3, 'b':0, 'c':2, 't':4} (DONT USE İNPUT .VERY İMPORTANT.)

Exercise 2: A vehicle inspection station keeps records of its checking services in a text file (called "inspection.txt"). Each line corresponds to a checking visit and contains the following information separated by slashes (*/"). The vehicle's registration number (serial number and series), the inspection performed (Assuming that there are four kind of services: Periodic, Pre- Sale, Emission, Other), and the service duration in minutes. The figure below shows a few lines of input file. Write a python program that asks the user to enter a vehicle registration number, then reads the input file and displays for each provided service on that vehicle, the total duration and the number of visits. Display an error using the proper exception if the file does not open/exist. Use exception to count and display the number of records having incorrect format of the data in the file (such as, serial number is not digit, unknown service category). Enter vehicle's registration number: 7203 RS…
