How about itertools.combinations?
import itertools
s = "LEQN"
for i in range(len(s)):
for comb in itertools.combinations(s, i+1):
print(comb)
Output:
('L',)
('E',)
('Q',)
('N',)
('L', 'E')
('L', 'Q')
('L', 'N')
('E', 'Q')
('E', 'N')
('Q', 'N')
('L', 'E', 'Q')
('L', 'E', 'N')
('L', 'Q', 'N')
('E', 'Q', 'N')
('L', 'E', 'Q', 'N')
For some reason I've got more 2-character combinations than you,
though.
