- Write a line of code to look at the first few rows of the DataFrame in Python import csv # take a look at the data survey = pd.read_csv('https://raw.githubusercontent.com/fivethirtyeight/data/master/steak-survey/steak-risk-survey.csv')

If a and b are two non-empty numerical row vectors (of the same length L) present in Matlab Workspace, what command would you use to create a new 2 x L matrix, called d, that is a combination of a and b (a elements are in the first row and elements of b are in the second row)?     d = transpose(a, b)     d = a _ b     d = [a; b]     d = a .* (1/b)

Question R   .Full explain this question and text typing work only     We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line

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. For…

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 row of…

a. Read the data in the file weatherAUS.csv into a Python dictionaryb. Show the first 5 lines to show that the data has been read in I've got the below but can't show the first 5 lines. Help? import csv # import csv with open('weatherAUS.csv') as dataFile: # opens the csv    dictreader = csv.DictReader(dataFile) # dictreader    for row in dictreader:            print(row) # prints all rows

Filename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py  Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list:     [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as:     ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”.  In this small example, we don’t achieve much of a savings (and indeed the…

Computer Science csv file "/dsa/data/all_datasets/texas.csv" Task 6: Write a function "county_locator" that allows a user to enter in a name of a spatial data frame and a county name and have a map generated that shows the location of that county with respect to other counties (by using different colors and/or symbols). Hint: function(); $county ==; plot(); add=TRUE.

Vector Creation (creating equally spaced vectors) Write a script with commands to create the following vectors and assign to the indicated variable names. ■ Create an evenly-spaced row vector A with elements starting at 0 and ending at 50 with increments of 0.5. ▪ Create a row vector B with 80 evenly-spaced elements starting at 0 and ending at л/2. Your code should not include the following MATLAB functions or keywords: for, while. Hint: one line of your solution should start with A = and the other line of your solution should start with B =
