[New-bugs-announce] [issue36413] Brief Tour of the Standard Library — Part II example problem

[YasirA]

New submission from YasirA <yarsanukaev at gmail.com>:

In the Template example, there's no placeholder to be substituted with date. I think it should be rewritten along the following lines:

    >>> import time, os.path
    >>> photofiles = ['img_1074.jpg', 'img_1076.jpg', 'img_1077.jpg']
    >>> class BatchRename(Template):
    ...     delimiter = '%'
    >>> fmt = input('Enter rename style (%d-date %n-seqnum %f-format):  ')
    Enter rename style (%d-date %n-seqnum %f-format):  Ashley_%d%n%f

    >>> t = BatchRename(fmt)
    >>> date = time.strftime('%d%b%y')
    >>> for i, filename in enumerate(photofiles):
    ...     base, ext = os.path.splitext(filename)
    ...     newname = t.substitute(d=date+'_', n=i, f=ext)
    ...     print('{0} --> {1}'.format(filename, newname))

    img_1074.jpg --> Ashley_0.jpg
    img_1076.jpg --> Ashley_1.jpg
    img_1077.jpg --> Ashley_2.jpg

Yasir.
