os.path.isdir(path) Return True if path is an existing directory. This follows symbolic links, so both islink() and isdir() can be true for the same path.

faulthandler.dump_traceback(file=sys.stderr, all_threads=True) Dump the tracebacks of all threads into file. If all_threads is False, dump only the current thread. Changed in version 3.5: Added support for passing file descriptor to this function.

name

os.supports_bytes_environ True if the native OS type of the environment is bytes (eg. False on Windows). New in version 3.2.

operator.__eq__(a, b) operator.__ne__(a, b) operator.__ge__(a, b) operator.__gt__(a, b) Perform “rich comparisons” between a and b. Specifically, lt(a, b) is equivalent to a < b, le(a, b) is equivalent to a <= b, eq(a, b) is equivalent to a == b, ne(a, b) is equivalent to a != b, gt(a, b) is equivalent to a > b and ge(a, b) is equivalent to a >= b. Note that these functions can return any value, which may or may not be interpretable as a Boolean value. See Comparisons for more inf

Unpacker.get_buffer() Returns the current unpack data buffer as a string.

runeval(expression, globals=None, locals=None) runcall(function, *args, **kwds) set_trace() See the documentation for the functions explained above.

os.fsdecode(filename) Decode filename from the filesystem encoding with 'surrogateescape' error handler, or 'strict' on Windows; return str unchanged. fsencode() is the reverse function. New in version 3.2.

bytearray.title() Return a titlecased version of the binary sequence where words start with an uppercase ASCII character and the remaining characters are lowercase. Uncased byte values are left unmodified. For example: >>> b'Hello world'.title() b'Hello World' Lowercase ASCII characters are those byte values in the sequence b'abcdefghijklmnopqrstuvwxyz'. Uppercase ASCII characters are those byte values in the sequence b'ABCDEFGHIJKLMNOPQRSTUVWXYZ'. All other byte values are uncased

class ctypes.c_void_p Represents the C void * type. The value is represented as integer. The constructor accepts an optional integer initializer.
