Python报错：not all arguments converted during string formatting

>>> d= ['ewf','2']
>>> if d[1]%2 ==0:
	print('defe')

	
Traceback (most recent call last):
  File "<pyshell#20>", line 1, in <module>
    if d[1]%2 ==0:
TypeError: not all arguments converted during string formatting

报错原因：定义列表的d [1]元素时，赋值的是'2'，是一个字符串，所以在执行d [1]％2时，前后格式不匹配所以报错

>>> c=['dgfre',3]
>>> if c[1]%2 == 1:
	print('dfgd')
