To allow other people to understand my code I've been using vbscript and trying to use the following pattern in all database operations: Open Connection Build Query Execute Query

问题 Is there any other way of getting a list of all unique characters in a textfile? I've tried the following way but is there a more pythonic way?

My best guess is that i need to change the file size.... can anyone help me please thanks 回答1: I guess that you need to open the file, seek to the end, delete characters and save it. seek ( http://docs.python.org/library/stdtypes.html#file.seek ) accepts negative values (e.g. f.seek(-3, os.SEEK_END) sets the position to the
