Question

到目前为止，应该由用户输入其名称帐号和余额，并将其输入列表。然后我要求他们输入他们的帐号，我应该从列表中而不是整个列表中打印出他们的特定号码，但是无法正常工作。

customers = list()
acctnum = list()
balance= list()

count = 0
while count != 2: 
    name = input("Enter your name: ")
    customers.append(name)
    num = int(input("Enter account number: "))
    acctnum.append(num)
    bal = input("Enter Current Balance:$ ")
    print()
    balance.append(bal)
    count = count + 1

print(customers)
print(acctnum)
print(balance)


personal = int(input("Enter account number: "))
print(personal)
if personal in acctnum:

   print(acctnum)

Answer 1

我发现字典在这样的应用程序中很有用：

accounts = {}

for x in range(2): 
    name = input("Enter your name: ")
    num = int(input("Enter account number: "))
    bal = input("Enter Current Balance: $")
    accounts[num] = {"name": name, "balance": bal}
    print()

for k, v in accounts.items():
    print(v["name"] + "'s account " + str(k) + " has $" + v["balance"])

personal = int(input("Enter account number: "))
if personal in accounts:
    print("Hello, " + accounts[personal]["name"] + " you have $" + accounts[personal]["balance"])

现在的数据存储在独立的列表中。您将必须使用诸如字典（在Python中实现）之类的关联数据类型来实现。

如何根据python中的用户输入在列表中打印某些项目？
