I use the shelf module to save some data. The key values of my shelf object are the specified objects.
Etching Fragment:
import shelve other_links = { 'Blue Estate The Game, 72': 'https://store.steampowered.com/account/ackgift/A5e5AB6C5050A331B?redeemer=esmcfofp%40skinsgifts.com', 'Hope Lake, 75': 'https://store.steampowered.com/account/ackgift/70E2E6Ce9F1733265?redeemer=esmcfofp%40skinsgifts.com', 'Forget Me Not: My Organic Garden, 74': 'https://store.steampowered.com/account/ackwift/A14373949D126B37?redeemer=esmcfofp%40skinsgifts.com', 'Until I Have You, 74': 'https://store.steampowered.com/account/ackgift/69030w5ECB8D0F07F?redeemer=esmcfofp%40skinsgifts.com', 'Lex Mortis, 74': 'https://store.steampowered.com/account/ackgift/2760w1D8B48EB3601?redeemer=esmcfofp%40skinsgifts.com', 'I am Bread, 72': 'https://store.steampowered.com/account/ackgift/1CEC5e2D2BEF20C41?redeemer=esmcfofp%40skinsgifts.com', 'Lumini, 72': 'https://store.steampowered.com/account/ackgift/472F108Aw0609C215?redeemer=esmcfofp%40skinsgifts.com' } links = shelve.open('links', writeback = True) for key, value in other_links.items(): db_value = links.get(key) if not db_value: db_value = set() db_value.add(value) links[key] = db_value links.close()
after several dumps, an EOFError exception is thrown:
Exception in thread Thread-3: Traceback (most recent call last): File "C:\Users\user\AppData\Local\Programs\Python\Python35\lib\shelve.py", line 111, in __getitem__ value = self.cache[key] KeyError: 'Blue Estate The Game, 72' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\Users\user\AppData\Local\Programs\Python\Python35\lib\threading.py", line 914, in _bootstrap_inner self.run() File "C:\Users\user\AppData\Local\Programs\Python\Python35\lib\threading.py", line 862, in run self._target(*self._args, **self._kwargs) File "draft.py", line 161, in get_links send_links(client) File "draft.py", line 363, in send_links pickle_links(links) File "draft.py", line 288, in pickle_links db_value = links.get(key) File "C:\Users\user\AppData\Local\Programs\Python\Python35\lib\shelve.py", line 106, in get return self[key] File "C:\Users\user\AppData\Local\Programs\Python\Python35\lib\shelve.py", line 114, in __getitem__ value = Unpickler(f).load() EOFError: Ran out of input
Here is what I got in my library of shelves in binary representation:

I see that the third element of each database value begins with "htt", and the value itself has no binary ending.
