- Frames Unlimited is a wholesaler that specializes in picture frames. The company stores its product information (each item’s number, name, size and price) in a sequential access file named pictureFrame.txt. You need to create a report using the pictureFrame.txt sequential access file. The report should contain a list of all picture frames with a size of 5×7. The report will be saved to another sequential access file named pictureFrame57.txt. Your first step is to ____. a. determine whether the pictureFrame.txt file exists b. declare a StreamReader variable for the input file c. open the pictureFrame.txt file for input using the OpenText method d. open the pictureFrame57.txt file for output using the CreateText method# Method: Load levelsList using the data in levelsFile def readLevelsFromFile(self): try: # Set levelsList to an empty list pass # Open the file pass # Use a loop to read through the file line by line pass # This code is inside the loop: # Convert the line to a float and then append it to levelsList pass # Close the file pass except: returnThe attached file USPopulation,txt contains the US population in thousands, during the years 1950 through 1990. The first line in the file contains the population for 1950, the second line contains the population for 1951, and so forth. Write a program that reads the file's contents into a list. The program should display the following data: the average annual growth in population during the time period the year with the greatest increase in population during the time period (highest growth rate) the year with the smallest increase in population during the time period (smallest growth rate) 151868 153982 156393 158956 161884 165069 168088 171187 174149 177135 179979 182992 185771 188483 191141 193526 195576 197457 199399 201385 203984 206827 209284 211357 213342 215465 217563 219760 222095 224567 227225 229466 231664 233792 235825 237924 240133 242289 244499 246819 249623
- 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.
