Can't evaluate tqdm as a boolean if disable is True #574
Description
If I convert a tqdm object to boolean to test for existence, I get an AttributeError if it was created with disable=True. Instead I would expect it to evaluate to False.
In [3]: pbar = tqdm(disable=False, total=100)
0%| | 0/100 [00:00<?, ?it/s]
In [4]: bool(pbar)
Out[4]: True
In [5]: pbar = tqdm(disable=True, total=100)
In [6]: bool(pbar)
