在元组内重复一个元组

Question

Is there a way to repeat a tuple inside a tuple ?

If I do something like

a = ((0, 1) * n)

I still get

a = (0, 1, 0, 1 ..... n times) 

what if I want something like

a = ((0, 1), (0, 1) ... n times)

Answer 1

Multiply a tuple with a tuple as its item. Don't forget a trailing , .

>>> ((0, 1),) * 5
((0, 1), (0, 1), (0, 1), (0, 1), (0, 1))

Answer 2

You might also be interested in a generator.

>>> def f():
...     for i in range(10):
...         yield (0, 1)
... 
>>> tuple(f())
((0, 1), (0, 1), (0, 1), (0, 1), (0, 1), (0, 1), (0, 1), (0, 1), (0, 1), (0, 1))
