oop - Python checking account simulator -

-

i have been working on oop program in python 3.0 simulates checking account , ran bug can't figure out. here is: in main part of program gave user multiple options such , exit, withdraw , deposit , , create new account. when user selects "create new account " program creates object , variable name has variable , im not sure how access atributes object labeled variable.basically asking is, how make variable name variable computer can keep track of , use access attributes of object? here program have far(if helps?):

class checking(object):     """a personal checking acount"""      def __init__(self , name, balance):         print("a new checking acount has been created")         self.name = name         self.balance = balance       def __str__(self):         rep = "balance object\n"         rep += "name of acount" + self.name + "\n"         rep += "balance " + self.balance + "\n"         return rep       def display(self):         print("\nyour acount name ",self.name)         print("your balance is",self.balance)       def deposit(self):         amount = int(input("\nplease enter amount of money wish diposit"))         self.balance += amount         print("\nthe balance of 'chris' ", self.balance)      def withdraw(self):         amount = int(input("\nplease enter amount wish withdraw "))         while amount > self.balance:             print("is invalid amount")             amount = int(input("\nplease enter amount wish withdraw "))         self.balance -= amount         print("\nthe balance of 'chris' ", self.balance)           answer = none      while answer != "0":         answer = input("""what action take?         0 exit         1 deposit         2 withdraw         3 add acount""")         if answer == "1":             input("ener pin").deposit()         if answer == "2":             input("enter pin ").withdraw()         if answer == "3":             input("enter num") = checking(name = input("\nwhat want acount name be?"), balance = 0)             input("enter pin").display()             print(checking)      input("\n\npress enter exit")

use dictionary; store accounts in accounts dictionary acount number key:

accounts = {}  # ... if answer == 3:     account_number = input("enter num")     account_name = input("\nwhat want acount name be?")     accounts[account_number] = checking(name=account_name, balance=0)

now can list accounts user has, example:

for account_number, account in accounts.items():     print('account number: {}, account name: {}'.format(account_number, account.name))

etc.

using local variables variable number of items same never idea. in case use lists or dictionaries instead.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
