未定义导入的变量

Question

目前正在尝试将我的代码从 "Original Program" 导入到 "Import"，该代码独立运行良好。我收到错误 "Date is not defined"。我假设错误与全局变量有关。我知道这一点，并花了一些时间试图自己解决这个问题，但无济于事。任何帮助表示赞赏:)

 **Original Program**   

def validDate(date, month, day):
    months = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
    days = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
    leapyear = ((date % 4) == 0) and ((date % 100) != 0) or ((date % 4) == 
    0) and ((date % 100) == 0) and ((date % 4000) == 0)
    if leapyear:
    days[1] += 1 
    valid = (day <= days[months.index(month)] and day > 0 and (1753 <= 
    date)) 
    print(valid)

date = int(input("Enter year: "))
month = int(input("Enter month: "))
day = int(input("Enter day: "))

validDate(date, month, day)


**Import**

from libHWDate import validDate

validDate(date, month, day)
