Enforce items at beginning and end of list

Question

How can I modify this list so that all p\'s appear at the beginning, the q\'s at the end, and the values in between are sorted alphabetically?

Answer 1

Solution to this question is:

1. First find all p and q elements in list.
2. Filter the original list.
3. Then, finally sort the list.

list = ['f','g','p','a','p','c','b','q','z','n','d','t','q'];
noOfPs = [i for i in l if i == 'p']; 
noOfQs = [i for i in l if i == 'q'];
resultList= noOfPs + sorted(filter(lambda x:x not in {'q', 'p'}, l))+ noOfQs
