regular expression question

i have particular lines in a data file that i want to parse using python. each line starts with the text "dataset" as a sort of markup

Code:

dataset .... \n

where the "...." is the data i am interested in. so i basically want to retrieve the whole line, then do some processing. so, my question is is there a way to create a regular expresion that matches 'dataset....\n' ? where the .... can be any string of characters? thanks for any thoughts.

Code:

^dataset.*$

That should work
