USE THE SIMPLE PYTHON CODE PLEASE The username code. The company can choose the specific criteria for the username. The criteria is as follows: a minimum length, a minimum number of capital letters, and a minimum number of special characters. Special charters are [,ドル #, ^, %, . etc]. You will turn in three .py files. The first file called main.py contains your main interface. The second file called functions.py contains all the functions your main code. The third file called parameters.py contains the parameters of the code: the special character list, the minimum length, the minimum number of special characters, the minimum number of capital letters, and the number of tries the user gets to input user name. Your code operates as follows. Display the criteria for the username. Prompt the user to input a username. If the username does not meet criteria, tell the user why and re prompt to enter in a username. Repeat until you reach the maximum number of tries allowed.

The given text files represent a list of account numbers and associated balances. Balances change over time. If a balance is later in the file, then this implies the balance for that customer is more recent. Ask the user for a file name then display the most recent balance along with the high and low balance. balances-0.txt customer id balance1 93ドル.831 805ドル.242 866ドル.454 943ドル.283 764ドル.121 798ドル.004 395ドル.595 644ドル.264 18ドル.314 814ドル.97

Suppose a csv file contains three comma-separated values (strings) on each line (see the leftcolumn of the example table below). Assume, each line of values are, respectively, thewidth, height, and depth of a box. Write a program called box.py and add thefollowing functions to this program.• read_file() takes a csv filename as a parameter that contains the widths, heights, anddepths of all boxes. This function must read the content of the file, store these values ina 2-D list as shown in the right column of the example table below, and return this list.All strings must be converted to integers before they are stored in the list. Example:csv data 2-D list[[15, 6, 3],[3, 7, 4],[6, 9, 3],[15, 6, 11],[6, 5, 5],[13, 10, 9],[9, 10, 3],[14, 5, 4],[4, 6, 11],[12, 10, 9]]• Add another function called max_volume() to this program that takes this 2-D list as aninput parameter. Each item in that list contains 3 integers representing the dimensions ofa box (i.e., width, height, depth). This...
