启用自动版式时，不能使用from typing import Dict class Convert: # Class Variables _my_dict: Dict = None # Import definitions def v1_0(self,my_dict): from format_utils import v1_0 as formatter return formatter.Formatter().format(my_dict) # Import definitions def v1_1(self,my_dict): from format_utils import v1_1 as formatter return formatter.Formatter().format(my_dict) # Function pointer dictionary # Must be defined after import functions import_format_util = \ { "1.0": v1_0,"1.1": v1_1,} def __init__(self,my_dict: Dict)-> None: # grab the format_version from dictionary passed in # for simplicity I am going to ignore any KeyErrors being thrown format_version: str = my_dict['format_version'] # Dynamically import the correct formatter using the dictionary of # function pointers,and pass my_dict into that formatter self._my_dict = self.import_format_util[format_version](self,my_dict) # I now have a correctly formatted dictionary to print print(self._my_dict) def main(): dict1 = \ { "format_version": "1.0","other_data": "Change Me!",} dict2 = \ { "format_version": "1.1",} # Initialize Convert object with first dict. __init__() will print dict init1 = Convert(dict1) # Initialize Convert object with second dict. __init__() will print dict init2 = Convert(dict2) main() 。最简单的方法是将Formatter与-setFrame一起使用。现在，您只需隐藏状态栏，堆栈视图便会删除状态栏并扩展滚动视图。
