print(char_type.value, byte_type.value, string_type.value, int_type.value) 输出: c_char(b'a') c_char(b'\x01') c_int(2) b'a' b'\x01' abc 2 (2)数组类型 数组的创建和C语言的类似,给定数据类型和长度即可,如下: # 数组# 定义类型char_array=c_char*3# 初始化char_array_obj=char...
Represents the C char datatype, and interprets the value as a single character. The constructor accepts an optional string initializer, the length of the string must be exactly one character. 翻译就是,c_char代表C中的char,在python中被视为单个字符,构造函数接受可选的字符串初始值设定项,字符串的...

注意Python 中没有像 C++ 表示的字符类型(char),所有的字符或串都被统一为 str 对象。如单个字符 c 的类型也为 str。 str 类型会被经常使用,先列举 5 个被高频使用的方法。 strip 用于去除字符串前后的空格: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 In [1]: ' I love python\t\n '.strip...

these function calls. None is passed as a C NULL pointer, bytes objects and strings are passed aspointer to the memory block that contains their data (char * or wchar_t *). Python integers are passed as theplatforms default C int type, their value is masked to fit into the C type. ...
