str, optional.

Prefix for the progressbar.

.RS

.RE

.TP

int, optional.

The number of expected iterations.

If unspecified, len(iterable) is used if possible.

As a last resort, only basic progress statistics are displayed (no ETA,

no progressbar).

If \f[C]gui\f[] is True and this parameter needs subsequent updating,

specify an initial arbitrary large positive integer, e.g.

int(9e9).

.RS

.RE

.TP

bool, optional.

If [default: True], keeps all traces of the progressbar upon termination

of iteration.

.RS

.RE

.TP

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).

.RS

.RE

.TP

float, optional.

Minimum progress display update interval, in seconds [default: 0.1].

.RS

.RE

.TP

float, optional.

Maximum progress display update interval, in seconds [default: 10].

Automatically adjusts \f[C]miniters\f[] to correspond to

\f[C]mininterval\f[] after long display update lag.

Only works if \f[C]dynamic_miniters\f[] or monitor thread is enabled.

.RS

.RE

.TP

int, optional.

Minimum progress display update interval, in iterations.

If 0 and \f[C]dynamic_miniters\f[], will automatically adjust to equal

\f[C]mininterval\f[] (more CPU efficient, good for tight loops).

If > 0, will skip display of specified number of iterations.

Tweak this and \f[C]mininterval\f[] 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.

.RS

.RE

.TP

bool, optional.

If unspecified or False, use unicode (smooth blocks) to fill the meter.

The fallback is to use ASCII characters \f[C]1\-9\ #\f[].

.RS

.RE

.TP

bool, optional.

Whether to disable the entire progressbar wrapper [default: False].

If set to None, disable on non\-TTY.

.RS

.RE

.TP

str, optional.

String that will be used to define the unit of each iteration [default:

it].

.RS

.RE

.TP

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 \f[C]total\f[] and \f[C]n\f[].

.RS

.RE

.TP

bool, optional.

If set, constantly alters \f[C]ncols\f[] to the environment (allowing

for window resizes) [default: False].

.RS

.RE

.TP

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].

.RS

.RE

.TP

str, optional.

Specify a custom bar string formatting.

May impact performance.

[default: \[aq]{l_bar}{bar}{r_bar}\[aq]], where l_bar=\[aq]{desc}:

{percentage:3.0f}%|\[aq] and r_bar=\[aq]| {n_fmt}/{total_fmt}

[{elapsed}<{remaining}, \[aq] \[aq]{rate_fmt}{postfix}]\[aq] Possible

vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt, percentage, rate,

rate_fmt, rate_noinv, rate_noinv_fmt, rate_inv, rate_inv_fmt, elapsed,

remaining, desc, postfix.

Note that a trailing ": " is automatically removed after {desc} if the

latter is empty.

.RS

.RE

.TP

int, optional.

The initial counter value.

Useful when restarting a progress bar [default: 0].

.RS

.RE

.TP

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).

.RS

.RE

.TP

dict or *, optional.

Specify additional stats to display at the end of the bar.

Calls \f[C]set_postfix(**postfix)\f[] if possible (dict).

.RS

.RE

.TP

float, optional.

[default: 1000], ignored unless \f[C]unit_scale\f[] is True.

.RS

.RE

.TP

chr, optional.

Delimiting character [default: \[aq]\[aq]].

Use \[aq]\[aq] for null.

N.B.: on Windows systems, Python converts \[aq]\[aq] to \[aq]\[aq].

.RS

.RE

.TP

int, optional.

String buffer size in bytes [default: 256] used when \f[C]delim\f[] is

specified.

.RS

.RE

.TP

bool, optional.

If true, will count bytes, ignore \f[C]delim\f[], and default

\f[C]unit_scale\f[] to True, \f[C]unit_divisor\f[] to 1024, and

\f[C]unit\f[] to \[aq]B\[aq].
