TypeError：“函数”对象不可下标 - Python

Question

我已尝试使用此代码解决作业：

bank_holiday= [1, 0, 1, 1, 2, 0, 0, 1, 0, 0, 0, 2] #gives the list of bank holidays in each month

def bank_holiday(month):
   month -= 1#Takes away the numbers from the months, as months start at 1 (January) not at 0. There is no 0 month.
   print(bank_holiday[month])

bank_holiday(int(input("Which month would you like to check out: ")))

但是当我运行它时，我得到了错误：

TypeError: 'function' object is not subscriptable

我不明白这是从哪里来的......

Answer 1

很简单，你有 2 个同名对象，当你说：bank_holiday[month] Python 认为你想运行你的函数并得到 ERROR。

只需将您的数组重命名为bank_holidays s”！像这样：

bank_holidays= [1, 0, 1, 1, 2, 0, 0, 1, 0, 0, 0, 2] #gives the list of bank holidays in each month

def bank_holiday(month):
   if month <1 or month > 12:
       print("Error: Out of range")
       return
   print(bank_holidays[month-1],"holiday(s) in this month ?")

bank_holiday(int(input("Which month would you like to check out: ")))

Answer 2

你可以用这个：

bankHoliday= [1, 0, 1, 1, 2, 0, 0, 1, 0, 0, 0, 2] #gives the list of bank holidays in each month

def bank_holiday(month):
   month -= 1#Takes away the numbers from the months, as months start at 1 (January) not at 0. There is no 0 month.
   print(bankHoliday[month])

bank_holiday(int(input("Which month would you like to check out: ")))

Answer 3

您有两个对象都命名为bank_holiday——一个是列表，一个是函数。消除两者的歧义。

bank_holiday[month] 引发错误，因为 Python 认为 bank_holiday 指的是函数（绑定到名称 bank_holiday 的最后一个对象），而您可能希望它指的是列表。
