#(1)check one y2 = np.array(ya) # [‘C‘,‘A‘] #this is what i not want
y2_test = y2.shape # 0-d
y2_test2 = y2.tolist() # dtype shows not list
#the right methon
#(2)check one
ls = ya.strip(‘][‘).split(‘,‘) # dtype show list
#(3) right methon
import ast
ls = ast.iteral_eval(ya)
ls = [i.strip() for i in ls]
