Jimin came to the fruit section of the supermarket. In the fruit section, there are three types of fruits, apple, pear, and melon. How many ways are there to buy all 6 fruits with these fruits?
3 1 [OP_SUB] 6 [OP_ADD] 6 [OP_COMB]
var_a = 3
var_b = 1
var_c = var_a - var_b
var_d = 6
var_e = var_c + var_d
var_f = 6
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))
