我在使用时间包时遇到问题

Im having trouble using the time package

每当我使用时间包时,我都会收到此错误:

Traceback (most recent call last):
  File "C:\Python3415\intrest calculator.py", line 53, in <module>
    time.sleep(1)
AttributeError: 'float' object has no attribute 'sleep'

这是我的代码:

    import time 

    while True:
        choice = input("will you like to calculate simple or compound intrest:")
        if choice == "simple intrest":
            userData(choice)
            time = time/12 
            intrest = principal * time * intrestRate
            intrest = round(intrest, 2)
            balance = principal + intrest
            balance = round(balance, 2) 
            balance = str(balance)
            intrest = str(intrest)
            print("your intrest is: %" + intrest) 
            time.sleep(1)  

            print("your final balance is $" + balance)

对不起各位,我才发现我的错误。

对于遇到相同问题的任何其他人,请确保 none 的变量与您的任何包相同。

对不起各位,是我的错。

应该从一开始就看到了
