Decrypt sintbit and convert to bool

[xyxiaoAk]

n is a sintbit.Array, and I want to iterate through each n[i] to determine whether to perform later operations:

n_reveal = n.reveal()
idx_list = []
for i in range(len(n_reveal)):
	if n_reveal[i]:
		idx_list.append(i)

In this way n_reveal[i] is a cint type of data and can't be conditioned, if I convert the condition from n_reveal[i] to n_reveal[i]==1, but n_reveal[i]==1 is of type regint and not of type bool. So what should I do to convert to a bool type condition to get the final idx_list
