>>> eth = {"eth0″:"192.168.1.1″}
>>> any(eth)
True
>>> eth = {}
>>> any(eth)
False
判断list是否为空
传统的方式:
复制代码 代码如下:
if len(mylist):
# Do something with my list
else:
# The list is empty
由于一个空 list 本身等同于 False,所以可以直接:
复制代码 代码如下:
if mylist:
# Do something with my list
else:
# The list is empty
希望本文所述对大家的Python程序设计有所帮助。
