如何在Python中将元组列表转换为元组的元组

Question

我正在尝试将元组列表转换为元组元组，我所做的事情是错误的，请帮助解决这个问题

list1= [('2', '297'), ('6', '297')]

for x in list1:
    print("inside fn")
    print(x)
    tuple_of_tuples+=tuple(x)
    print(tuple_of_tuples)

输出=('2', '297', '6', '297') 我想要输出为(('2', '297'), ('6', '297'))

Answer 1

In [1]: list1= [('2', '297'), ('6', '297')]

In [2]: tuple(list1)
Out[2]: (('2', '297'), ('6', '297'))
