Usage:
  tqdm [--help | options]

Options:
  -h, --help     Print this help and exit.
  -v, --version  Print version and exit.
  --desc=<desc>  : str, optional
            Prefix for the progressbar.
  --total=<total>  : int or float, optional
            The number of expected iterations. If unspecified,
            len(iterable) is used if possible. If float("inf") or as a last
            resort, only basic progress statistics are displayed
            (no ETA, no progressbar).
            If `gui` is True and this parameter needs subsequent updating,
            specify an initial arbitrary large positive number,
            e.g. 9e9.
  --leave  : bool, optional
            If [default: True], keeps all traces of the progressbar
            upon termination of iteration.
            If `None`, will leave only if `position` is `0`.
  --ncols=<ncols>  : int, optional
            The width of the entire output message. If specified,
            dynamically resizes the progressbar to stay within this bound.
            If unspecified, attempts to use environment width. The
            fallback is a meter width of 10 and no limit for the counter and
            statistics. If 0, will not print any meter (only stats).
  --mininterval=<mininterval>  : float, optional
            Minimum progress display update interval [default: 0.1] seconds.
  --maxinterval=<maxinterval>  : float, optional
            Maximum progress display update interval [default: 10] seconds.
            Automatically adjusts `miniters` to correspond to `mininterval`
            after long display update lag. Only works if `dynamic_miniters`
            or monitor thread is enabled.
  --miniters=<miniters>  : int or float, optional
            Minimum progress display update interval, in iterations.
            If 0 and `dynamic_miniters`, will automatically adjust to equal
            `mininterval` (more CPU efficient, good for tight loops).
            If > 0, will skip display of specified number of iterations.
            Tweak this and `mininterval` to get very efficient loops.
            If your progress is erratic with both fast and slow iterations
            (network, skipping items, etc) you should set miniters=1.
  --ascii=<ascii>  : bool or str, optional
            If unspecified or False, use unicode (smooth blocks) to fill
            the meter. The fallback is to use ASCII characters " 123456789#".
  --disable  : bool, optional
            Whether to disable the entire progressbar wrapper
            [default: False]. If set to None, disable on non-TTY.
  --unit=<unit>  : str, optional
            String that will be used to define the unit of each iteration
            [default: it].
  --unit-scale=<unit_scale>  : bool or int or float, optional
            If 1 or True, the number of iterations will be reduced/scaled
            automatically and a metric prefix following the
            International System of Units standard will be added
            (kilo, mega, etc.) [default: False]. If any other non-zero
            number, will scale `total` and `n`.
  --dynamic-ncols  : bool, optional
            If set, constantly alters `ncols` and `nrows` to the
            environment (allowing for window resizes) [default: False].
  --smoothing=<smoothing>  : float, optional
            Exponential moving average smoothing factor for speed estimates
            (ignored in GUI mode). Ranges from 0 (average speed) to 1
            (current/instantaneous speed) [default: 0.3].
  --bar-format=<bar_format>  : str, optional
            Specify a custom bar string formatting. May impact performance.
            [default: '{l_bar}{bar}{r_bar}'], where
            l_bar='{desc}: {percentage:3.0f}%|' and
            r_bar='| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, '
              '{rate_fmt}{postfix}]'
            Possible vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt,
              percentage, elapsed, elapsed_s, ncols, nrows, desc, unit,
              rate, rate_fmt, rate_noinv, rate_noinv_fmt,
              rate_inv, rate_inv_fmt, postfix, unit_divisor,
              remaining, remaining_s, eta.
            Note that a trailing ": " is automatically removed after {desc}
            if the latter is empty.
  --initial=<initial>  : int or float, optional
            The initial counter value. Useful when restarting a progress
            bar [default: 0]. If using float, consider specifying `{n:.3f}`
            or similar in `bar_format`, or specifying `unit_scale`.
  --position=<position>  : int, optional
            Specify the line offset to print this bar (starting from 0)
            Automatic if unspecified.
            Useful to manage multiple bars at once (eg, from threads).
  --postfix=<postfix>  : dict or *, optional
            Specify additional stats to display at the end of the bar.
            Calls `set_postfix(**postfix)` if possible (dict).
  --unit-divisor=<unit_divisor>  : float, optional
            [default: 1000], ignored unless `unit_scale` is True.
  --write-bytes  : bool, optional
            If (default: None) and `file` is unspecified,
            bytes will be written in Python 2. If `True` will also write
            bytes. In all other cases will default to unicode.
  --lock-args=<lock_args>  : tuple, optional
            Passed to `refresh` for intermediate output
            (initialisation, iterating, and updating).
  --nrows=<nrows>  : int, optional
            The screen height. If specified, hides nested bars outside this
            bound. If unspecified, attempts to use environment height.
            The fallback is 20.
  --colour=<colour>  : str, optional
            Bar colour (e.g. 'green', '#00ff00').
  --delay=<delay>  : float, optional
            Don't display until [default: 0] seconds have elapsed.
  --delim=<delim>  : chr, optional
            Delimiting character [default: '\n']. Use '\0' for null.
            N.B.: on Windows systems, Python converts '\n' to '\r\n'.
  --buf-size=<buf_size>  : int, optional
            String buffer size in bytes [default: 256]
            used when `delim` is specified.
  --bytes  : bool, optional
            If true, will count bytes, ignore `delim`, and default
            `unit_scale` to True, `unit_divisor` to 1024, and `unit` to 'B'.
  --tee  : bool, optional
            If true, passes `stdin` to both `stderr` and `stdout`.
  --update  : bool, optional
            If true, will treat input as newly elapsed iterations,
            i.e. numbers to pass to `update()`. Note that this is slow
            (~2e5 it/s) since every input must be decoded as a number.
  --update-to  : bool, optional
            If true, will treat input as total elapsed iterations,
            i.e. numbers to assign to `self.n`. Note that this is slow
            (~2e5 it/s) since every input must be decoded as a number.
  --null  : bool, optional
            If true, will discard input (no stdout).
  --manpath=<manpath>  : str, optional
            Directory in which to install tqdm man pages.
  --comppath=<comppath>  : str, optional
            Directory in which to place tqdm completion.
  --log=<log>  : str, optional
            CRITICAL|FATAL|ERROR|WARN(ING)|[default: 'INFO']|DEBUG|NOTSET.
