python assert

-point types, and strings It is relatively simple to use the three data types of integer, floating-point, and string in the C language extension of Python, just know how to build and maintain them. The following example shows how to use Python in the C language for these three types of data: Case 2:TYPEIFS.C Build an integer pyobject* pint = Py_buildvalue ("I", 2003);

. Python's C language interface provides some macros to maintain the reference count. The most common is to use py_incref () to increase the reference count of Python objects by 1, and use py_decref () to reduce the reference count of Python objects by 1. Python defines six data types: integer, floating point, String, tuples, lists, and dictionaries, first, you

Python exception handling summary, python exception handling Recently, a small project often encounters Python exceptions, which can be a headache. Therefore, we need to organize exceptions to avoid confusion next time. The following describes how to organize Python exceptions. 1.
