USB条码扫描仪研究
我正在对一个(大型)图书编目项目进行一些可行性研究。如果有好的信息来源,我将不胜感激,但我特别想知道的是:
1.)python 是否有任何与条形码阅读器(最好是 USB)一起使用的模块?还有哪些其他程序可用于读取条形码信息?
2.)通过一些信息来源可能可以更好地回答这个问题,但是我应该在条形码扫描仪中寻找什么样的东西,特别是当我想要扫描书籍上的大量条形码时。
3.)这也可以通过一些信息来源来更好地回答,书籍的条形码中标准存储了什么样的信息。
我知道这相对偏离主题,但任何帮助将不胜感激。
I'm doing some feasibility research with regards to a (large) book cataloging project. Any help would w/r/t good sources of information would be appreciated but the things I would specifically like to know are:
1.)does python have any modules for use with barcode readers (preferably USB)? What other programs are available for reading barcode information?
2.)This may be better answered with a few sources of information, but what kinds of things should I look for in a barcode scanner, especially if I'm looking to scan, specifically, a lot of barcodes on books.
3.)This may also be better answered with a few sources of information, what kind of information is stored standard in a book's barcode.
I know this is relatively off-topic, but any help would be greatly appreciated.

您正在制作 python Web 应用程序还是客户端应用程序?除非您正在寻找专门的条形码扫描功能,否则这并不重要,因为扫描仪的输入看起来像键盘输入(有时以特殊输入字符为前缀),因此您只需要有一种监听键盘的方法即可输入并捕获该特殊字符。
Are you making a python web-app or a client application? Unless you're looking for specialized bar code scanning functionality it doesn't really matter since the input from the scanner appears like keyboard entry (sometimes prefixed with a special input character), so you just have to have a way of listening to the keyboard input and catching that special character.
