class tqdm():
def update(self, n=1):
"""
Manually update the progress bar, useful for streams
such as reading files.
E.g.:
>>> t = tqdm(total=filesize) # Initialise
>>> for current_buffer in stream:
... ...
... t.update(len(current_buffer))
>>> t.close()
The last line is highly recommended, but possibly not necessary if
``t.update()`` will be called in such a way that ``filesize`` will be
exactly reached and printed.
Parameters
----------
n : int or float, optional
Increment to add to the internal counter of iterations
[default: 1]. If using float, consider specifying ``{n:.3f}``
or similar in ``bar_format``, or specifying ``unit_scale``.
Returns
-------
out : bool or None
True if a ``display()`` was triggered.
"""
def close(self):

def clear(self, nomove=False):

def refresh(self):
"""
Force refresh the display of this bar.
Parameters
----------
nolock : bool, optional
If ``True``, does not lock.
If [default: ``False``]: calls ``acquire()`` on internal lock.
lock_args : tuple, optional
Passed to internal lock"s ``acquire()``.
If specified, will only ``display()`` if ``acquire()`` returns ``True``.

def unpause(self):

Resets to 0 iterations for repeated use.
Consider combining with ``leave=True``.
Parameters
----------
total : int or float, optional. Total to use for the new bar.
"""
def set_description(self, desc=None, refresh=True):

Set/modify description of the progress bar.
Parameters
----------
desc : str, optional
refresh : bool, optional
Forces refresh [default: True].

def set_postfix(self, ordered_dict=None, refresh=True, **tqdm_kwargs):

Set/modify postfix (additional stats)

Parameters
----------
ordered_dict : dict or OrderedDict, optional
refresh : bool, optional
Forces refresh [default: True].

Use ``self.sp`` to display ``msg`` in the specified ``pos``.

``self.some_frontend(**self.format_dict)`` instead of ``self.sp``.
Parameters
----------
msg : str, optional. What to display (default: ``repr(self)``).
pos : int, optional. Position to ``moveto``
(default: ``abs(self.pos)``).
