ctypes — A foreign function library for Python — Python 3.13.3 ...
3 days ago · Fundamental data types, when returned as foreign function call results, or, for example, by retrieving structure field members or array items, are transparently converted to native Python types. In other words, if a foreign function has a restype of c_char_p , you will always receive a Python bytes object, not a c_char_p instance.
Built-in Types — Python 3.13.3 documentation
2 days ago · There are three basic sequence types: lists, tuples, and range objects. Additional sequence types tailored for processing of binary data and text strings are described in dedicated sections. Common Sequence Operations¶ The operations in the following table are supported by most sequence types, both mutable and immutable.
