通过内容功能在Python中的另一个模块 [英] Pass Content To Function of Another Module in Python

问题描述

我使用SAX解析器。我试图发送'内容'我检索使用下面code：

I am using SAX Parser. I am trying to send the 'content' I retrieved using below code:

检查的startElement和endElement之后，我有低于code：

After checking the startElement and endElement, I have the below code:

def characters(self, content):  
   text =  format.formatter(content)

这format.formatter预计将读取该数据，我被作为内容进行任何处理，如消除垃圾字符等，并返回。我这样做，通过使用与string.replace功能：

this format.formatter is expected to read this data that I sent as 'content' for any processing like removing junk characters etc and return it. I do that by using string.replace function:

    remArticles = {' ! ':'', ' $ ':''}

    for line in content:
        for i in remArticles:
            line= line.replace(i, remArticles[i])
        #FormattedFileForIndexing.write(line)
            return line

但是输出不上来了预期。

However the output is not coming up as expected.

这将是巨大的，如果有人可以帮助这一点。

It will be great if some one can help on this.

源将一些事情，如：

噢！那是很多和$$$$ 1000

"Oh! That's lots and 1000s of $$$$"

预计：哦，那是很多1000的

Expected: Oh That's lot of 1000s

推荐答案

您遍历每个字符不是每一行：

You are iterating over each character not each line:

def characters(content):
    remArticles = {'!': '', '$': ''} # remove spaces from " ! "
    for i in remArticles:
         content = content.replace(i, remArticles[i])
    return content

您也尝试匹配！和 $ 与周围空间而根据您的预计输出不正确

You are also trying to match ! and $ with spaces around them which according to your expected output is incorrect.

In [6]: content =  "Oh! That's lots and 1000s of $$$$"

In [7]: characters(content)
Out[7]: "Oh That's lots and 1000s of "

只需使用取而代之的是最有效的选择：

Just using replace is the most efficient option:

In [20]: timeit characters(content)
1000000 loops, best of 3: 746 ns per loop

In [21]: timeit format_this(content)
100000 loops, best of 3: 2.57 µs per loop
