You need to match and capture the characters (The extract method accepts a regular expression with at least one capture group.) after http: other than /, 1 or more times. It can be done with: <code>df.col.str.extract(r'http:([^/]+)/landing')</code>
Your regex matches http:/, then 0+ / symbols as few as possible and then /landing.
where [^/]+ is a negated character class that matches 1+ occurrences of characters other than /.
