There are 4 female students and 3 male students. If one female student and one male student want to be in charge of weekly duty, in how many ways can you choose students to be in charge of weekly duty?
4 1 [OP_COMB] 3 1 [OP_COMB] [OP_MUL]
var_a = 4
var_b = 1
var_c = 1
var_a = int(var_a)
var_b = int(var_b)
for i, elem in enumerate(range(var_b)):
    var_c = var_c * (var_a-i)
for i, elem in enumerate(range(var_b)):
    var_c = var_c / (i+1)
var_d = 3
var_e = 1
var_f = 1
var_d = int(var_d)
var_e = int(var_e)
for i, elem in enumerate(range(var_e)):
    var_f = var_f * (var_d-i)
for i, elem in enumerate(range(var_e)):
    var_f = var_f / (i+1)
var_g = var_c * var_f
print(int(var_g))
