并删除''00:00:00.00'的所有实例,我会使用

无需regexp:


someString = someString.replace(&00:00:00.00) ","")


我建议您在打印出值之前执行此操作,

而不是尝试扫描整页之后你会打印出来。

I have a python-cgi file that pulls data from an sql database, i am
wondering what is the easiest way to remove all instances of
''00:00:00.00'' in my date column.

how would i write a python script to scan the entire page and delete all
instances of ''00:00:00.00'', would i use regular expressions?

No need for a regexp:

someString = someString.replace("00:00:00.00", "")

I''d recommend doing it before you print the values out,
rather than try and "scan the entire page" after you''ve
printed them.

Easy ''nuff.

You could use regular expressions or you might want to take a look at
Beautiful Soup http://www.crummy.com/software/BeautifulSoup
to parse the page and replace the offending text.

umm. if you''re using a database, why not filter out uninteresting dates either
in the SQL statement, or when you''re building the page ?
