通过合并元组元素获取元组列表的产品？

您可以itertools.chain.from_iterable像这样简单地使用扁平化内部元组

for product in p:
    print tuple(itertools.chain.from_iterable(product))

例如，

>>> from itertools import chain, product
>>> [tuple(chain.from_iterable(prod)) for prod in product(*lists)]
[(1, 4), (1, 5), (1, 6), (2, 4), (2, 5), (2, 6), (3, 4), (3, 5), (3, 6)]
