Question

In this problem, you will need to create a state machine that stimulates a simple bank account in Python 3.6. Any withdrawal when the balance is less than $100 incurs a $5 charge. The state machine should fulfill the following:

• The starting balance is specified when instantiating the object.

• The output of the state machine is the current balance after the transaction.

Sample interaction:

>>> acct = SimpleAccount (110)

>>> acct . start ()

>>> acct . step (10)

120

>>> acct . step ( -25)

95

>>> acct . step ( -10)

80

>>> acct . step ( -5)

70

>>> acct . step (20)

90

>>> acct . step (20) 110

Answer 1

Code with indenatation:

Output:

____________________________________________________________________________________

Code:

import threading
class SimpleAccount(threading.Thread):
balance=0
  
def __init__(self,b):
threading.Thread.__init__(self) #handling thread
self.balance = b #setting value
def step(self,val):
if(val<0): #val is negative
if(self.balance >100): #if bal greater than 100
self.balance=self.balance+val
print(self.balance)
else:
self.balance=self.balance+(val-5) #bal is less than 100 then -5 extra
print(self.balance)
else: #if val is postive
self.balance=self.balance+val #adding value
print(self.balance)
  

  
acct=SimpleAccount(110)
acct.start()
acct.step(10)
acct.step(-25)
acct.step(-10)
acct.step(-5)
acct.step(20)
acct.step(20)
