    re.findall(r"Test([0-9.]*[0-9]+)", text)

    


    or, a bit shorter:
    


    re.findall(r"Test([\d.]*\d+)", text)

    


    By the way - you do not need to escape the dot in a character class. Inside [] the . has no special meaning, it just matches a literal dot. Escaping it has no effect.
