Python: find all possible word combinations with a sequence of characters (word segmentation)

Question

I\'m doing some word segmentation experiments like the followings.

lst is a sequence of characters, and output is all the possible words.

Answer 1

#!/usr/bin/env python
from itertools import combinations
a = ['a', 'b', 'c', 'd']
a = "".join(a)
cuts = []
for i in range(0,len(a)):
    cuts.extend(combinations(range(1,len(a)),i))
for i in cuts:
    last = 0
    output = []
    for j in i:
        output.append(a[last:j])
        last = j
    output.append(a[last:])
    print(output)

output:

zsh 2419 % ./words.py  
['abcd']
['a', 'bcd']
['ab', 'cd']
['abc', 'd']
['a', 'b', 'cd']
['a', 'bc', 'd']
['ab', 'c', 'd']
['a', 'b', 'c', 'd']
