I have to create a program that will create a database when using geo points. I will include a previous program and the instructions: You are going to change program 8 so that instead of reading in a list of five or more points from a file you will read the points in from a database. Create a program the will create your database and insert at least five points. Use your own data, something like: 100, 200, 123, Main Campus 120, 133, 142, Montoya 153, 123, 322, Rio Rancho 133, 123, 143, STEMULUS Center 153, 142, 122, ATC Run your initialization code to create the database. Modify your GUI program from program 8 so that it reads points from your database instead of a file. Turn in the initialization code, the database and your new GUI program.

Description (for python please) This is a command line program, dl_cu.py that accepts two parameters: a root directory a best before date in the form YYYY-MM-DD Based on these inputs dl_cu.py generates a report lists all of the files thathaven't been modified since the best before date. The output includes: The full path of each file The modification date of the file The file file size in MB After presenting the user with this list it will ask them if they would like todelete all of of the listed files and any empty directories stored in the root directory.
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.
2. Geraldine's Landscaping Service and Gerard's Lawn Maintenance are merging their businesses and want to merge their customer files. Each file contains a customer number, last name, address, and property area in square feet, and each file is in customer number order. Design the logic for a program that merges the two files into one file containing all customers. Assume there are no identical customer numbers.
Instructions Your job is to write a program to encrypt outgoing messages and decrypt incoming messages using a Vigenere Cypher. In this assignment, you will parse a string of words from a file into tokens using the strtok_s command with pointers and then use the Vigenere Cypher algorithm to encrypt and decrypt the parsed words. Before you can perform any encryption/decryption activities, the first step is to read in messages from a file and parse the messages into individual words. The Program: Setting up classes and understanding tokenization The first step in encrypting/decrypting messages is to parse the messages into words before applying the encryption/decryption algorithms to them. This parsing process is called “tokenization.” Read the contents of a file into this array using the getline command. The objective of this assignment is to demonstrate the use of pointers in a program utilizing c-strings and tokenization. The use of pointers is foundational in C++. This…
2. This involves a .txt file with one thousand rows of random numbers (between 1-1000) Using Python, create a program to perform this task, with 3 methods of doing this: Read the entire contents of file1.txt into memory, then process each row. Read one row of file1.txt at a time and process it. Split file1.txt into 2 parts and read each part into memory separately.
