How to judge the equality of objects in python

The first are the = = and equal methods of strings in C #. "=":

For built-in value types, = = determines whether two memory values are equal.

For user-defined value types (Struct), = = needs to be overloaded, otherwise it cannot be used.

For reference types, true is returned by default with the same reference, but the system overloads many reference types (such as string mentioned below), so the comparison of reference types in c # is not recommended. "equals":

For value types, memory equals to return true.

For reference types, pointing to the same reference is equal.

But what is special is the string String, which is a special referential type. In the C # language, the equals () method of string is overloaded to make the string object work as if it were a value type. = in python

The object in python contains three elements: id, type, and valueid are used to identify a unique object, type identifies the type of object, and value is used to set the value of the object. Is determines whether it is an object or not, using id to determine.

= = is to determine whether the value of an object is the value of b object, and its _ _ eq__ method is called by default.

What does python mean Python is a cross-platform, interpretive, compiled, interactive and object-oriented scripting language, originally designed to write automated scripts, and is often used to develop independent and large-scale projects as versions are constantly updated and new features are added.
