If you cut a piece of string that is 12 centimeters (cm) in half, choose one of the cut pieces and cut it in half again, find the length in centimeters (cm) of the current shortest piece of string.
12 2 [OP_DIV] 2 [OP_DIV]
var_a = 12
var_b = 2
var_c = var_a / var_b
var_d = 2
var_e = var_c / var_d
print(int(var_e))
