Does python's regular expression have anything equivalent to match numbers in a given range?

For example in bash, you can match test19.txt, test20.txt, test21.txt by test{19..21}.txt

I am **not** looking for regular expression to match all digits like [1-2][0-9].

I want to match only a particular series of numbers starting from some number to another.

Update: The final aim is to create a regexp object with re.compile(), so that i can use it to search a big list of strings.
