【Python面试真题】-how do I iterate over a sequence in reverse order? for x in reversed(sequence): ... # do something with x.. 如果不是list, 最通用但是稍慢的解决方案是: for i in range(len(sequence)-1, -1, -1): x = sequence[i] <do something with x>...
You can use the built-in dir() function to get a list of methods and attributes that any Python object provides. If you run dir() with an empty dictionary as an argument, then you’ll get all the methods and attributes of the dict class:...
