Python: Generating all ordered combinations of a list

Question

I\'m using Python 2.7.

I\'m having a list, and I want all possible ordered combinations.

import itertools
stuff = [\"a\",\"b\",\"c\", \"d\"]
for L in

I think you mean in continuous order by "in correct order", in this case you just need use two pointers to iterator over stuff:

stuff = ["a","b","c", "d"]
# sort stuff here if it's not sorted

result = []
for i in xrange(len(stuff)):
    for j in xrange(i+1, len(stuff)+1):
        result.append(stuff[i:j])

# sort the result by length, maybe you don't need it
result = sorted(result, key=len)

for r in result:
    print ' '.join(r)
