Question

Def transfer(bank, log_in, usera, userb, amount): ''' in this function, you will try to make a transfer between two user accounts. bank is a dictionary where the key is the username and the value is the user's account balance. log_in is a dictionary where the key is the username and the value is the user's log-in status. amount is the amount to be transferred between user accounts (usera and userb). amount is always positive. what you will do: - deduct the given amount from usera and add it to userb, which makes a transfer. - you should consider some following cases: - usera must be in the bank and his/her log-in status in log_in must be true. - userb must be in log_in, regardless of log-in status. userb can be absent in the bank. - no user can have a negative amount in their account. he/she must have a positive or zero balance. return true if a transfer is made. for example:

Answer 1

Using the knowledge in computational language in python this code will be described for bank is a dictionary where the key is the username and the value is the user's account balance.

Writing code in python:

def transfer (bank, log_in, userA, userB, amount):

if userA in bank and log_in[userA]:

 if userB in log_in:

   if amount <= bank [userA]:

     bank [userA] -= amount

     bank[userB] += amount

     return true

 return false

 bank= {"Bradon": 115.5, "Patrick": 18.9, "Sarah": 827.43, "Jack": 45.0, "James": 128.87}

 log_in= {"Bradon": False, "Jack": False, "James": False, "Sarah": False}

 transfer(bank, log_in, "Bradon", "Jack", 100)
