Hello, I try to learn python by following the audicity page. Now I have the following problem. I have two strings a and b Now I have to check if the characters of b are all in a. But they do have to be in the same order. So I thought about this solution. length = len(b) start = 1 while start < length : check = a.find (b[start]) if check == -1 : return False start = start + 1 return True But according to the site this can be solved in a one-liner. So can someone give me pointers how this can be done and if my solution can work. Roelof
