处理Sharma的详细例外
原标题:Handling detailed exception in Python

我正在从<代码>测试.xls文档中处理数据读物,如:

from sys import exe_info
    try:
        book = xlrd.open_workbook( test.xls )
        sh = book.sheet_by_index(0)
        for row in range( 1, sh.nrows ):
            for index, value in enumerate(sh.row_values(row)):
                process_value(value)
    except:
        print exc_info()[1]

如果在处理<代码>过程中出现例外情形——价值(价值),则该条目中有一些错误。 但在印刷<代码>exc_info( ) ***时。 我得以接受例外描述,如:

 ascii  codec can t encode characters in position 7-10: ordinal not in range(128)

但是,如果我印刷<代码>exc_info(>功能,则按产出提供。

(<type  exceptions.UnicodeEncodeError >, UnicodeEncodeError( ascii , u bokor bxe3u0192xe2xa9la , 7, 11,  ordinal not in
range(128) ), <traceback object at 0x01067080>)

因此,如果我想对用户作例外处理,那么用户就会在<条码>的某一行文上受到质疑,该编码表示出错误。 因此,在<代码>exc_info(>上。 我可以看到这个词。

u bokor bxe3u0192xe2xa9la 

This is the word from XLS file. If we can t show for which line error is raise if I at lease show that above word it will help to find that word and remove that word. I am not able to get that particular word from exc_info() or is their is any better way to handle this situation?

最佳回答

<代码>xlrd 将所有文本电池的内容作为unicode的标语。 你们不需要知道“正确的编码”——它有密码。

我建议你这样做:

for row in xrange(1, sh.nrows):
    for index, value in enumerate(sh.row_values(row)):
        try:
            process_value(value)
        except:
            print >> sys.stderr, row, index, repr(value)
            raise

这使你能够显示所有相关数据,然后重新提出例外,以便你获得格式错误的信息和为你进行的追踪。

如果你要向我们展示您的<条码>程序——价值功能——你是否试图<条码>明确或暗含地试图打上<条码>。
