Get an iterable object, and return an iterator which acts exactly like the
    iterable, but prints a progress meter and updates it every time a value is
    requested.
    'desc' can contain a short string, describing the progress, that is added
    in the beginning of the line.
    'total' can give the number of expected iterations. If not given,
    len(iterable) is used if it is defined.
    'file' can be a file-like object to output the progress message to.
    If leave is False, tqdm deletes its traces from screen after it has
    finished iterating over all elements.
    If less than mininterval seconds or miniters iterations have passed since
    the last progress meter update, it is not updated again.
