python - 匹配 *text* 的正则表达式是什么？

Question

要匹配this is *some text*.但不匹配的正则表达式是什么this is \*another \*text。正则表达式应该匹配星号之间的文本。

Answer 1

pattern = "\*(\w+(?:\s+\w+)*)\*"
re.findall(pattern, "this is *some text*.") // return 'some text'
re.findall(pattern, "this is \*another \*text") // return nothing

用“$”替换“*”：

subpattern = "(\*(\w+(?:\s+\w+)*)\*)"
re.sub(subpattern, r"$\2$", "this is *some text*.") // return 'this is $some text$.'
