[(100ryan,200kim),(100music,200math)......], 
[(100ryanmusic),(200kimmath).....]

Answer 1

https://docs.python.org/2/library/itertools.html#itertools.combinations

example:

import itertools

data = 'ABC'
for i in range(1, len(data) + 1):
    comb = itertools.combinations(data, i)
    print(list(comb))

output:

[('A',), ('B',), ('C',)]
[('A', 'B'), ('A', 'C'), ('B', 'C')]
[('A', 'B', 'C')]
