# 符串然后再网络传输,而接收端也应该可以通过某种机制进行解包还原出原始的结构体数据。python中的struct模块就提供了这样 # 的机制,该模块的主要作用就是对python基本类型值与用python字符串格式表示的C struct类型间的转化(This module # performs conversions between Python values and C structs represented as Py...

# performs conversions between Python values and C structs represented as Python strings.)。stuct模块 # 提供了很简单的几个函数,下面写几个例子。该模块作用是完成Python数值和C语言结构体的Python字符串形式间的转换。这可以 # 用于处理存储在文件中或从网络连接中存储的二进制数据,以及其他数据源。
” and he replied “Python.” I learned some Fortran, Cobol, and IBM Basic in college, then “other” versions of Basic when the PC came along. Since then I had acquired a decent skill-set with VBA. I had never heard of Python. We started out together programming Rock-Scissors-Paper....

在C/C++中,高级数据类型和低级数据类型的区别更加明显。C/C++中的高级数据类型(如structs或classes)需要明确地声明和定义,而Python中的高级数据类型则有内置的创建和操作方式,这使得Python在处理复杂数据类型时更加灵活和简洁。这一部分的讲述,引用了Python之禅中的一句话:“Simple is better than complex.”(简单...
To call a method, call the method of the same name on the proxy object, passing in the interface name via the dbus_interface keyword argument: 为了调用一个方法,在 proxy object 上调用同样名称的方法,通过 dbus_interface 关键词参数传递接口的名称。
This is why you need to define an array of PyMethodDef structs: C static PyMethodDef FputsMethods[] = { {"fputs", method_fputs, METH_VARARGS, "Python interface for fputs C library function"}, {NULL, NULL, 0, NULL} }; Each individual member of the struct holds the following info...
