In Python 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. Ex: If the input of the program is: movies.csv and the contents…
Can someone please look at my script and explain why the data is not being read and entered into my pretty table? Any help is appreciated. Script is below. I am getting an empty pretty table as my output. # Python Standard Library import os from prettytable import PrettyTable myTable = PrettyTable(["Path", "File Size", "Ext", "Format", "Width", "Height", "Type"]) dirPath = input("Provide Directory to Scan:") i f os.path.isdir(dirPath): fileList = os.listdir(dirPath) for eachFile in fileList: try: localPath = os.path.join(dirPath, eachFile) absPath = os.path.abspath(localPath) ext = os.path.splitext(absPath)[1] filesizeValue = os.path.getsize(absPath) fileSize = '{:,}'.format(filesizeValue) except: continue # 3rd Party Modules from PIL import Image imageFile = input("Image to Process: ") try: with Image.open(absPath) as im: # if success, get the details imStatus = 'YES' imFormat = im.format imType = im.mode imWidth = im.size[0] imHeight = im.size[1] #print("Image Format: ", im.format)…
Please Assist me to complete the Python Code: Data frames can be subset by a chosen value using ==. Ex: df[df.x == 5] gives all the rows in the data frame df for which the column x has a value of 5. Write a program that performs the following tasks: Load the file mtcars.csv into a data frame called df Create a new data frame df_cyl by subsetting the data frame based on a user defined value for the column cyl. Print the shape of the new data frame.mtcars.csv should not be necessary to answer this question. Please advise on the commands for subsetting a new data frame and for printing the shape of the new data frame. Thank You! Please try Completing the Program Below: import pandas as pd cylinders = int(input()) df = # read in the csv file mtcars.csv df_cyl = # create a new dataframe with only the rows where cyl = cylinders print(# print the shape of the new data frame)

My Python program analyzes data from a CSV file that is all numbers. This program is designed to find the median and standard deviation I'm trying to figure out a part where if the last column of the file contains zeros, it finds where the numbers are in the same row indexes of the other columns. It then calculates the average of these numbers. However, my program calculates them by columns first, not by rows. How could this be fixed? For example, if the last column had a zero and another column had a three in the same row index and another with 4, those numbers would be calculated. # Lucas Conklin# 5772707import csvimport statistics def readCSVIntoDictionary(f_name): data = [] with open(f_name) as f: reader = csv.reader(f) for row in reader: if not data: for index in range(len(row)): data.append([]) for index in range(len(row)): data[index].append(float(row[index])) f.close() return…
