【问题描述】：

我正在从网站上抓取文本，我正在使用 python 中的 strip 函数来删除这些换行符和尾随空格，并将所有逗号替换为空格。但是它什么也没做

            # print(predesc[0].div.p)
            itemDesc = predesc[0].div.p.text
            # itemDesc= str(itemDesc).strip("\\t\\n")
            itemDesc.strip()
            itemDesc.strip("\t")
            itemDesc.strip("\n\n")
            itemDesc.replace(",","")











            print(repr(itemDesc))```
output is
"                        Shortcut the learning curve with an all-around board that''s catch-free and easy for boosting confidence anywhere you take it.\n\nSome riders just want to get straight to the fun part.

【问题讨论】：

strip() 返回一个新值...它不会更改原始字符串。你需要像itemDesc = itemDesc.strip() 这样的东西。

将您想要删除尾随空格的内容分配给变量。然后打印出来。

谢谢你，我知道它确实去掉了空格，但 \n\n 没有被条纹

与从任何其他数据中删除尾随空格的方法相同。

【参考方案1】：

itemDesc = itemDesc.replace('  ',' ').replace(',','').replace("''","'").replace("\n","").strip()
