Pycallable_check (func)) {fprintf (stderr, "call_func:expected a callable\n"); Goto fail; }/* Build arguments/* use Py_buildvalue () to construct the parameter tuple or dictionary */args = Py_buildvalue ("(DD)", x, y); Kwargs = NULL; /* Call the function */* use Pyobject_call () to pass a callable object to i

This article mainly introduces several examples of code that is compatible with Python and Python 3.x, in Python2.7.x, because some Python 3 code writing features are used, it is possible to write compatibility code in some origin

Http://docs.cython.org/src/quickstart/cythonize.html Cython is a Python compiler. This means the it can compile normal Python code without changes (with a few obvious exceptions of some As-yet D language Features). However, for performance critical code, it are often helpful to add static type declarations, as they wo

to eject a CD driver, or a Web service to delete a cached file in the/tmp directory, or a socket service to bind a TCP port, these calls are not expected when you unit tests. As a developer, you're more concerned about whether your library has successfully invoked a system function to eject a CD, rather than experiencing a CD tray opening every time you test. As a developer, you are more concerned about whether your library successfully invokes the system function to eject the CD (with the co

when using Python, a feature is a document string in Python, The document string is also known as docstrings. Use the document string to add descriptive documentation to our modules, classes, and functions, making the program easier to read. This seems to be no different from the annotations in other languages, however, the document strings in Python are special

executes, a represents the memory unit address unchanged, and its value is updated to 2.As for the above Python naming rule, I have written a simple note before , and I will not dwell on it. The above rules are easy to understand, but in actual engineering projects, it is possible to inadvertently introduce bugs to the code by neglecting the " assignment-binding " feature (an experienced C/s

you want to write a script to pop up a CD driver, or a Web service to delete a cache file in the/tmp directory, or a socket service to bind a TCP port, these calls are not expected in your unit testing. As a developer, you are more concerned about whether your library has successfully called system functions to eject CDs, rather than experiencing each test with the CD tray open. As a developer, you are more concerned about whether your library has successfully called system functions to eject C

I learned the Python list and wrote a function to output the list. This time, I will continue to learn how to share the code we have compiled with the PyPI community, the print_lol function written in the above article is used as an example. To share the print_lol function, we first need to encapsulate this function into a module. The so-called module is actually an object. the file at the end of py. Here w

Code like a pythonista:idiomatic PythonIf you have a C + + foundation, it is relatively easy to learn another language. Because C + + is process oriented and object oriented. It is very low level, can access the machine like C, it is also very advanced, there are templates, STL and so on. If I read the deep C + + object model carefully, I think other languages will not be more complicated than this. The more you know about C + +, the more
