name : type, optional

TODO: find out why this is needed.
|
|
delim : chr, optional
|
|
Delimiting character [default: '\n']. Use '\0' for null.
|
|
N.B.: on Windows systems, Python converts '\n' to '\r\n'.
|
|
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 : str, optional
|
|
Directory in which to install tqdm man pages.
|
|
comppath : str, optional
|
|
Directory in which to place tqdm completion.
