Question

I have a string dt = '301 302 303' how can I get different combinations of above string with considering only spaces while splitting the string.

# output
301
302
303
301 302
301 303
302 303
301 302 303

Answer 1

Please use itertools module turn the string to a list and then iterate

dt = '301 302 303' 
import itertools
list1 = dt.split()
for i in range(1,len(list1) + 1):
    for subset in itertools.combinations(list1,i):
        print(subset)

output

('301',)
('302',)
('303',)
('301', '302')
('301', '303')
('302', '303')
('301', '302', '303')
