// this is the error i get: IndentationError: expected an indented block

Answer 1

Its IndentationError.
complete the class definition.

class  BankAccount:
  def  _init_(self,balance):
    self.balance  =  balance
  def  deposit(self,amount):
    self.balance  +=  amount
    return  self.balance
  def  withdraw(self,amount):
    if  amount>self.balance:
        print  "invalid  transaction"
    else:
        self.balance  -=  amount
        return  self.balance

class  MinimumBalanceAcccount(BankAccount):
  def __init__(self):
    print "working"
