String conversion and formatting
Extending and Embedding the Python Interpreter
These functions are useful when creating your own extension functions and methods. Additional information and examples are available in Extending and Embedding the Python Interpreter.
Formats such as y* and s* fill a Py_buffer structure. This locks the underlying buffer so that the caller can subsequently use the buffer even inside a Py_BEGIN_ALLOW_THREADS block without the risk of mutable data being

Other formats take a str or a read-only bytes-like object, such as bytes, and provide a const char * pointer to its buffer. In this case the buffer is “borrowed”: it is managed by the corresponding Python object, and sha
This format does not accept bytes-like objects. If you want to accept filesystem paths and convert them to C character strings, it is preferable to use the O& format with PyUnicode_FSConverter() as converter.

These formats allow representing Python numbers or single characters as C numbers. Formats that require int, float or complex can also use the corresponding special methods __index__(), __float__() or __complex__() to co
Tests the value passed in for truth (a boolean predicate) and converts the result to its equivalent C true/false integer value. Sets the int to 1 if the expression was true and 0 if it was false. This accepts any valid P
