Question

What is the regex to match this is *some text*. but not this is \*another \*text. The regex is supposed to match the texts between the asterisks.

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

For replacing ‘*’ with ‘$’:

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