<PY>转换类型：嵌套列表的遍历

万能的字符串

嵌套列表的遍历

a= [1, 2, 3, 4, [5, 6], [7, 8],[9,10, [11,12]]]print(13 in [ int(i) for i in str(a).replace("[","").replace("]","").split(',')])b= [1, 2, 3, 4, [5, 6], [7, 8],[9,10, [11,12]]]print(str(7) in str(b))

字典的比较

"".join({1:2,3:4,5:6,'a':'b','c':{1:2}})=="".join({1:2,3:4,5:6,'a':'b','c':{1:2}})
