我收到“元组”对象无法作为错误调用

Question

brackets = set([(()())])
Stack = []
StackSize = 20
ch=(['(',')'])
arr=[]

Here I have generated a set of brackets which is showing an error. How can it be corrected?

Answer 1

Actually, the tuple inside your expression is being called using another tuple expression ()

>>> ()()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object is not callable
>>> 

I think you want to create a string similar to following as string values. For example:

   >>> brackets = set('[','(','()','()',')',']')

Answer 2

它应该是

brackets = set('[','(','(',')','(',')',')',']')
