Tôi tin rằng bạn muốn một cái gì đó như thế này:
một danh sách các thuộc tính từ một đối tượng
Chức năng tích hợp dir[] có thể làm công việc này.
Lấy từ đầu ra help[dir] trên vỏ Python của bạn:
dir[...]
dir[[object]] -> list of stringsNếu được gọi không có đối số, hãy trả lại tên trong phạm vi hiện tại.
Khác, trả về một danh sách các tên bao gồm [một số] các thuộc tính của đối tượng đã cho và của các thuộc tính có thể truy cập được từ nó.
Nếu đối tượng cung cấp một phương thức có tên
0, nó sẽ được sử dụng; Nếu không thì logic Dir [] mặc định được sử dụng và trả về:$ python Python 2.7.6 [default, Jun 22 2015, 17:58:13] [GCC 4.8.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> a = "I am a string" >>> >>> type[a] >>> >>> dir[a] ['__add__', '__class__', '__contains__', '__delattr__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__', '__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '_formatter_field_name_split', '_formatter_parser', 'capitalize', 'center', 'count', 'decode', 'encode', 'endswith', 'expandtabs', 'find', 'format', 'index', 'isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'partition', 'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill']

ĐọcPython all[] function returns true if all the elements of a given iterable [List, Dictionary, Tuple, set, etc.] are True otherwise it returns False. It also returns True if the iterable object is empty. Sometimes while working on some code if we want to ensure that user has not entered a False value then we use the all[] function.
Bàn luận
Hàm python all [] trả về đúng nếu tất cả các yếu tố của một số không thể sử dụng được [danh sách, từ điển, tuple, set, v.v.] là đúng nếu không nó trả về sai. Nó cũng trả về đúng nếu đối tượng có thể trống. Đôi khi trong khi làm việc trên một số mã nếu chúng tôi muốn đảm bảo rằng người dùng chưa nhập giá trị sai thì chúng tôi sử dụng hàm All [].all[ iterable ]
- Chức năng python all [] trong Python It is an iterable object such as a dictionary,tuple,list,set,etc.
Cú pháp: Tất cả [có thể lặp lại]boolean
Có thể sử dụng được: Đó là một đối tượng có thể lặp lại như từ điển, tuple, danh sách, bộ, v.v.

Làm cách nào để kiểm tra các phương thức trong Python?
Cách đơn giản nhất để có được danh sách các phương thức của bất kỳ đối tượng nào là sử dụng lệnh help [].Nó sẽ liệt kê tất cả các phương pháp có sẵn/quan trọng liên quan đến đối tượng đó.use the help[] command. It will list out all the available/important methods associated with that object.
Làm cách nào để liệt kê tất cả các phương thức trong mô -đun Python?
Chúng tôi có thể liệt kê tất cả các hàm có trong mô -đun Python bằng cách sử dụng phương thức Dir [] trong vỏ Python hoặc trong Shell Promption Shell.using the dir[] method in the Python shell or in the command prompt shell.
Làm thế nào để bạn sử dụng tất cả các phương thức trong Python?
Chức năng python - tất cả [] hàm python tất cả [] trả về đúng nếu tất cả các phần tử của một số không thể sử dụng được [danh sách, từ điển, tuple, set, v.v.] là đúng nếu không nó sẽ trả về sai.Nó cũng trả về đúng nếu đối tượng có thể trống.returns true if all the elements of a given iterable [List, Dictionary, Tuple, set, etc.] are True otherwise it returns False. It also returns True if the iterable object is empty.
Tất cả [] trong Python là gì?
Python tất cả [] hàm chức năng tất cả [] trả về đúng nếu tất cả các mục trong một điều có thể là đúng, nếu không nó sẽ trả về sai.Nếu đối tượng có thể xóa, hàm tất cả [] cũng trả về true.returns True if all items in an iterable are true, otherwise it returns False. If the iterable object is empty, the all[] function also returns True.
