0 reply content: first, Python is a language. Therefore, Cpython, Jython, and Pypy are implemented based on their implementations. CPython uses the C language to implement Python and Its Interpreter (JIT compiler). Jython is implemented using the Java language, and Pypy is implemented using Python (precisely a Python subset ). It is like English is also divided into the United States, Britain, Australia and other English, its syntax is figured out, but the implementation of the class library is

. The difference is that building blocks of code is used to initialize all objects uniformly, and to locate the initialization content of different object commonalities. The constructor is the initialization of the corresponding object. This: can be used to represent a reference to the object to which the function belongs. In a nutshell, which object is calling the function where this is located, this represents which object. When defining a function in a class, the function is used interna
