Minsu wants to put 2 Korean and 2 English workbooks next to each other on the bookshelf. If each workbook is different, how many ways can he put the Korean workbooks next to each other?
2 1 [OP_ADD] 2 1 [OP_ADD] [OP_PERM] 2 [OP_MUL]
var_a = 2
var_b = 1
var_c = var_a + var_b
var_d = 2
var_e = 1
var_f = var_d + var_e
var_g = 1
var_c = int(var_c)
var_f = int(var_f)
for i, elem in enumerate(range(var_f)):
    var_g = var_g * (var_c-i)
var_h = 2
var_i = var_g * var_h
print(int(var_i))
