Pythonic在python 2.4中模拟itertools.product的方法

def product(*args):
    if not args:
        return [[]]
    else:
        first, rest = args[0], args[1:]
        rest_product = product(*rest)
        return [ [x] + y for x in first for y in rest_product ]

# 示例用法
A = [1, 2]
B = [3, 4]
C = [5, 6]

result = product(A, B, C)
print(result)

[[1, 3, 5], [1, 3, 6], [1, 4, 5], [1, 4, 6], [2, 3, 5], [2, 3, 6], [2, 4, 5], [2, 4, 6]]
