Jungkook is going to the mart to pick out snacks. If you are trying to choose 5 snacks out of 20, how many ways are possible to choose them?
20 1 [OP_SUB] 5 [OP_ADD] 5 [OP_COMB]
var_a = 20
var_b = 1
var_c = var_a - var_b
var_d = 5
var_e = var_c + var_d
var_f = 5
var_g = 1
var_e = int(var_e)
var_f = int(var_f)
for i, elem in enumerate(range(var_f)):
    var_g = var_g * (var_e-i)
for i, elem in enumerate(range(var_f)):
    var_g = var_g / (i+1)
print(int(var_g))
