traceback_limit Maximum number of frames stored in the traceback of traces: result of the get_traceback_limit() when the snapshot was taken.

lineno Line number (int).

asyncio.iscoroutinefunction(func) Return True if func is determined to be a coroutine function, which may be a decorated generator function or an async def function.

fill(text) Wraps the single paragraph in text, and returns a single string containing the wrapped paragraph.

shlex.eof Token used to determine end of file. This will be set to the empty string (''), in non-POSIX mode, and to None in POSIX mode.

read(size=-1) Read at most size bytes from the chunk (less if the read hits the end of the chunk before obtaining size bytes). If the size argument is negative or omitted, read all data until the end of the chunk. An empty bytes object is returned when the end of the chunk is encountered immediately.

HMAC.hexdigest() Like digest() except the digest is returned as a string twice the length containing only hexadecimal digits. This may be used to exchange the value safely in email or other non-binary environments. Warning When comparing the output of hexdigest() to an externally-supplied digest during a verification routine, it is recommended to use the compare_digest() function instead of the == operator to reduce the vulnerability to timing attacks.

binascii.a2b_hqx(string) Convert binhex4 formatted ASCII data to binary, without doing RLE-decompression. The string should contain a complete number of binary bytes, or (in case of the last portion of the binhex4 data) have the remaining bits zero.

ctypes.memset(dst, c, count) Same as the standard C memset library function: fills the memory block at address dst with count bytes of value c. dst must be an integer specifying an address, or a ctypes instance.

ctypes.wstring_at(address, size=-1) This function returns the wide character string starting at memory address address as a string. If size is specified, it is used as the number of characters of the string, otherwise the string is assumed to be zero-terminated.
