Python csv.writer将带引号的字符串写入文件,而不是实际字符串
我正试图将一个列表写入文件。即使字符串周围没有引号,csv.writer也会使用引号写入字符串。我用了.strip来去掉引号,当我打印出来检查时,它打印的很好Python csv.writer将带引号的字符串写入文件,而不是实际字符串,python,Python,我正试图将一个列表写入文件。即使字符串周围没有引号,csv.writer也会使用引号写入字符串。我用了.strip来去掉引号,当我打印出来检查时,它打印的很好 # -*- coding: utf-8 -*- ''' ############################################################################## Scrape wiki pages with localities in the US.

要仅在绝对需要时发出引号,请在创建编写器时添加csv.QUOTE_MINIMAL或csv.QUOTE_NONE参数:
writer = csv.writer(csvfile, delimiter=',',csv.QUOTE_MINIMAL)
作家之间有细微的差别,但基本用法是一样的:
csv.QUOTE_MINIMAL指示writer对象仅引用包含特殊字符(如分隔符、引号或lineterminator中的任何字符)的字段
csv.QUOTE_NONE:指示writer对象从不引用字段。当当前分隔符出现在输出数据中时,它前面会有当前转义字符。如果未设置escapechar,则如果遇到任何需要转义的字符,写入程序将引发错误
即使csv.QUOTE_NONE在数据必须被引用时也会发出引号,例如:数据中的引号,如果不转义,这将使csv无法读取。try writer=csv.writerscsvfile,delimiter=',',csv.QUOTE_
