Convert a Python string to a C pointer to a character string. You must not provide storage for the string itself; a pointer to an existing string is stored into the character pointer variable whose address you pass. The C string is null-terminated. The Python string must not contain embedde...
ok = PyArg_ParseTuple(args, "s", &s); /* A string */ /* Possible Python call: f('whoops!') */ ok = PyArg_ParseTuple(args, "lls", &k, &l, &s); /* Two longs and a string */ /* Possible Python call: f(1, 2, 'three') */ ok = PyArg_ParseTuple(args, "(ii)...
这样一旦参数解析失败,就会调用PyErr_SetString函数来打印错误信息,并继续执行函数体内的代码。这样可以提高函数的鲁棒性,使其在参数解析失败时不会直接崩溃。 第二篇示例: Python是一种非常流行的计算机编程语言,广泛应用于各种领域,从Web开发到科学计算。在Python中,有许多内置的模块和函数,可以帮助开发者更轻松地完成...

How to PyArg_ParseTuple the bytearray in Python to C? For example, in Python, array = bytearray(bytes(random.choice(range(256)) * length)) and sometimes we want to pass this byte array to C using the PyArg_ParseTuple function (Python-C Library). We can c
"s" (string or Unicode object) [char *] 将Python字符串或Unicode对象转换为指向字符串的C指针。不能为字符串本身提供存储;指向现有字符串的指针存储在您传递地址的字符指针变量中。C字符串以NULL结尾。Python字符串不能包含嵌入的空字节;如果有,就会引发TypeError异常。使用默认编码将Unicode对象转换为C字符串。
