用類和對(duì)象實(shí)現(xiàn)一個(gè)銀行賬戶的資金交易管理, 包括存款、取款和打印交易詳情, 交易詳情中包含每次交易的時(shí)間、存款或者取款的金額、每次交易后的余額。
如:

下面按照要求定義一個(gè)賬戶 Account 類。賬戶 Account 類的屬性:
1. 當(dāng)前賬戶金額 money
2. 當(dāng)前賬戶交易日志 account_logs
賬戶 Account 類的方法:
1. 存錢 deposit()無返回值
2. 取錢 withdrawl()無返回值
3. 打印交易詳情 transaction_log()無返回值
案例代碼如下:
#coding: utf-8
import time
import prettytable as pt
money = 0
acount_logs = []
class Account:
def __init__(self):
global money
self.money = money
self.acount_logs = acount_logs
def deposit(self):
amount = float(input('存入金額:'))
self.money += amount
self.write_log(amount,'轉(zhuǎn)入')
def withdrawl(self):
amount = float(input('取出金額:'))
if amount > self.money:
print('余額不足')
else:
self.money -= amount
self.write_log(amount,'取出')
def transaction_log(self):
tb = pt.PrettyTable()
tb.field_names = ["交易日期","摘要","金額","幣種","余額"]
for info in self.acount_logs:
if info[1] =='轉(zhuǎn)入':
amount = '+{}'.format(info[2])
else:
amount = '-{}'.format(info[2])
tb.add_row([info[0],info[1],amount,'人民幣',info[3]])
print(tb)
def write_log(self,amout,handle):
create_time = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))
data =[create_time,handle,amout,self.money]
self.acount_logs.append(data)
def show_menu():
""" 顯示菜單欄 """
menu = """

"""
print(menu)
if __name__ == '__main__':
show_menu()
account = Account()
while True:
