Python 3 Given that a variable named pathName contains a string describing a directory path, write a single Python statement that will store the names of all files and subdirectories in that path in a List structure named contents. DO NOT traverse the path/directory. You are only interested in the immediate path and its contents. You may assume that any necessary import statements already exist.

Python S3 Get File In the Python file, write a program to get all the files from a public S3 bucket named coderbytechallengesandbox. In there there might be multiple files, but your program should find the file with the prefix and cb - then output the full name of the file. You should use the boto3 module to solve this challenge. You do not need any access keys to access the bucket because it is public. This post might help you with how to access the bucket. Example Output ob name.txt Browse Resources Search for any help or documentation you might need for this problem. For exampler array indexing, Ruby hash tables, etc.

A declared name is only valid within a region of code known as the name's scope. Example: A variable "globalVar_1" declared in main() is only valid within main(), from the declaration to main()'s end. True or false

in c# i need to Write the program named DirectoryInformation that allows a user to continually enter directory names until the user types end. If the directory name exists, display a list of the files in it; otherwise, display the following message, Directory foo does not exist, to indicate the directory does not exist (foo would be the name of the directory to be checked) . Create as many test directories and files as necessary to test your program. An example of the program is shown below: Enter a directory >> lorem lorem contains the following files lorem/ipsum.txt Enter another directory or type end to quit >> foo Directory foo does not exist

In C++ PLEASE Use the text file from Chapter 12, forChap12.txt. SEE BELOW Write a program that opens a specified text file then displays a list of all the unique words found in the file. Addition to the text book specifications, print the total of unique words in the file. Text File = forChap12.txt No one is unaware of the name of that famous English shipowner, Cunard. In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric tons. Eight years later, the company's assets were increased by four 650-horsepower ships at 1,820 metric tons, and in two more years, by two other vessels of still greater power and tonnage. In 1853 the Cunard Co., whose mail-carrying charter had just been renewed, successively added to its assets the Arabia, the Persia, the China, the Scotia, the Java, and the Russia, all ships of top speed and, after the Great Eastern, the biggest ever...

Design a program that reads a file called sales.txt containing the following data: Jane, 215.5,445.5,910.0 John, 825.0,250.5,675.0 Bill,0.0,999.15 Each line has a employee's name and their weekly sales totals all separated by commas. Some employees have taken vacation some weeks so no numbers are captured for those weeks. Create a function that takes a list of floats and returns the average value for those numbers. After reading the information from the file, use a for loop to calculate the sales average using your new average function for each employee and display the following output to the screen. Jane, average sales: 523.67 John, average sales: 583.50 Bill, average sales: 499.56

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...

Create a C++ program containing a deque container that possesses the unique property of expanding at both its front and back ends. Initially, the deque holds the elements (2, 3, 4). Modify the program to include values 1 and 5, inserting 1 at the front and 5 at the back. Consequently, when the program is executed, the deque container should exhibit the values (1, 2, 3, 4, 5).

Design an application for the ABC Company that will process inventory from a file called ABC_Inventory.txt (attached to this assignment). The file contains Item ID, Description and list price stored on a separate line in the file. The program should display the contents of each record and then calculate and display the average list price. it is important that this is done in Thonny for python w

<<Write in Java>> - Challenge 7 File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file

Need help to implement networking in python Server.py Load data from file This option will ask the user for a fully qualified path and will load a JSON file containing the information for users and pending messages. The format of the JSON file will be defined based on your implementation and it will the same used to save the data into file (menu option #4). Functionalities the server must provide: 1) User Sign Up: adds a user identified by a phone number to the system. a) Protocol: USR|username|password|display_name b) Response: 0|OK for success. 1| for an error. c) The server should validate that the username does not exist 2) User Sign In: verify user credentials a) Protocol: LOG|username|password b) Response: i) 0|OK → the credentials are correct. ii) 1|Invalid Credentials iii) 2|Already Logged In → in case that the user is logged in from another client. c) This will help the server knowing which user is connected. d) The server should keep a list of connected clients, which should...

The Directory class has a list of names in it. You should use dynamic memory to create anarray upon instantiation. You should create a copy constructor for the directory class and anassignment operator (i.e. operator=()). You should create a function called fillDirectory whichaccepts a size for the directory and the names for it both of which should be given by the user.In main, create directory1 and fill it with information. Use the assignment operator=() to setdirectory2 equal to directory1. This is in c++
