在執行這個我收到提示說:Python對象()不帶參數
D:\SARFARAZ\Python>Python assignment_01.py
Traceback (most recent call last):
File "assignment_01.py", line 35, in <module>
BankAcc1 = BankAcc('Sarfaraz',12345,50000)
TypeError: object() takes no parameters
代碼:
#Assignment_01 : Class Creation
class BankAcc(object):
int_rate = 0.7
balance = 0
#def **_init_**(self, name, number, balance): --> error was in this line, I've corrected it now as below
def __init__(self, name, number, balance):
self.name = name
self.number = number
self.balance = balance
def withdraw(self, amount):
self.balance -= amount
return self.balance
def deposit(self, amount):
self.balance += amount
return self.balance
def add_interest(self):
self.interest = int_rate * self.balance
self.balance += self.interest
return self.balance
'''class MinimumBalanceAccount(BankAccount):
def __init__(self, min_bal):
BankAccount.__init__(self)
self.min_bal = 500
def withdraw(self, amount):
if self.balance - amount < self.min_bal:
print ("Sorry, minimum balance must be maintained.")
else:
BankAccount.withdraw(self, amount)'''
BankAcc1 = BankAcc('Sarfaraz',12345,50000)
BankAcc2 = BankAcc1.withdraw(1000)
print (BankAcc2)
我試圖創建一個對象,然後試圖調用退出()方法 和撤回一些金額後打印餘額。
我怎麼會這麼傻,錯過了.. !!!感謝@Martijn Pieters – sarfarazit08
