假设我有长文本。从以下文本中，我只需要抽象部分。如何避免{{ }} 之间的文本。谢谢 `

{{ Info extra text}}
{{Infobox film

| released       = 1986
| runtime        = 144 minutes

 was a German-born theoretical physicist who developed the theory of general relativity, effecting a
 revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics 
 and one of the most prolific intellects in human history.`

我做了什么：

>>> text
"{{ Info extra text}}\n{{Infobox film\n| name           = Papori\n| released       = 1986\n| runtime        = 144 minutes\n| country        = Assam, {{IND}}\n| budget         = [[a]]\n| followed by    = free\n}}\nAlbert Einstein ( /'ælb?rt 'a?nsta?n/; German: ['alb?t 'a?n?ta?n] ( listen); 14 March 1879 – 18 April 1955)\n was a German-born theoretical physicist who developed the theory of general relativity, effecting a\n revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics \n and one of the most prolific intellects in human history.`"
>>> re.sub(r"\{\{[\w\W\n\s]*\}\}", "", text)
"\nAlbert Einstein ( /'ælb?rt 'a?nsta?n/; German: ['alb?t 'a?n?ta?n] ( listen); 14 March 1879 – 18 April 1955)\n was a German-born theoretical physicist who developed the theory of general relativity, effecting a\n revolution in physics.

编辑：巴特的评论是正确的。

可以考虑这个替代方案：

>>> re.sub(r"\{\{[^\}]*\}\}", "", "{{a\n   oaheduh}} b {{c}} d")
' b  d'

【讨论】：

匹配第一个{{，然后消耗直到最后一个}}。这可能适用于 OP 发布的（单个）示例，但也会删除 "{{a}} b {{c}}" 中的 "b"。
另外，您可以从[\w\W\n\s] 中删除\n\s，这些集合已经与\W 匹配。
