如何使用for循环来缩短代码？Python

我基本上是从用户那里获取信息，将输入放在一个列表中，并要求他们提供帐号。我还让他们在另外两个列表中输入姓名和余额。我希望它只打印他们的具体号码、姓名和余额，基于他们使用循环而不是if和elif输入的账号

 count = 0
    while count != 4: 
    name = input("Enter your name: ")
    customers.append(name)
    num = int(input("Enter account number: "))
    acctnum.append(num)
    bal = float(input("Enter Current Balance:$ "))
    print()
    balance.append(bal)
    count = count + 1
personal = int(input("Enter account number: "))
withdraw = int(input("Enter amount to be withdrawn: "))


if personal in acctnum:

   if (acctnum.index(personal)) == 0:
       print()
       print("\nCustomer name: ", customers[0])
       print("Account Number: ",acctnum[0])
       print("Balance: ", balance[0])
       newbal = balance[0] 
       print()

   elif (acctnum.index(personal)) == 1:
      print("\nCustomer name: ", customers[1])
      print("Account Number: ",acctnum[1])
      print("Balance: ", balance[1])
      newbal = balance[1] 
      print()

   elif (acctnum.index(personal)) == 2:
      print("\nCustomer name: ", customers[2])
      print("Account Number: ",acctnum[2])
      print("Balance: ", balance[2])
      newbal = balance[2] 
      print()

   elif (acctnum.index(personal)) == 3:
      print("\nCustomer name: ", customers[3])
      print("Account Number: ",acctnum[3])
      print("Balance: ", balance[3])
      newbal = balance[3] 
      print()

   elif (acctnum.index(personal)) == 4:
      print("\nCustomer name: ", customers[4])
      print("Account Number: ",acctnum[4])
      print("Balance: ", balance[4])
      newbal = balance[4] 
      print()

类似于此循环结构的内容将减少必要的

elif

语句：

if personal in acctnum:
    for i in range(4):
        if (acctnum.index(personal)) == i:
            print()
            print("\nCustomer name: ", customers[i])
            print("Account Number: ",acctnum[i])
            print("Balance: ", balance[i])
            newbal = balance[i] 
            print()

对于范围（4）中的i，始终可以使用跟踪帐户数的变量替换

中的4
 也许你想修正你的缩进。你发布的内容甚至不会运行。
