return re.search("something.*is", "something is written here") is not None
it returns a match object if the string was found or None otherwise.
you dont need to care about the match object in your case but it can
become handy when you add groups in the regular expression.
the "." stands for "any character" and "*" for any number of the preceding
object, so ".*" matches for a string of any length with any character in it
you don't need the wildcard at the beginning or at the end as regexps have
special characters for start ("^") and end ("$").

at first regular expressions may look strange but when you get used to them
you won't understand how you could have lived so long without them ;-)
