2-12python use any to determine whether an object is empty

This article mainly introduces Python using any method to determine whether an object is empty, and gives an improved method for everyone to compare the reference, with a certain reference value, the need for friends can refer to the next

The example in this article describes how Python uses any to determine whether an object is empty. Share to everyone for your reference.

The specific implementation code is as follows:

>>> eth = {"Eth0″:"192.168.1.1″}>>> any (ETH) True >>> eth = {}>>> any (ETH) False

The traditional way:

if Len (mylist):     # Do something with my list Else :     # The list is empty

Because an empty list itself is equivalent to False, you can directly:

if mylist:     # Do something with my list Else :     # The list is empty
