　　When you want to pass the argument is already a list, the function calls to accept separate parameters, this time can consider the parameter list split: You can use the * operator to automatically disassemble the parameter list: args=[3,6]x=list (range (*args))print x-------------------Output-----------------------------[3, 4, 5] You can use the * * operator to split the keyword argument into a dictionary: defParrot (voltage,state='a stiff', action='Voom'): Print

() function expects a separate start and stop parameters.If they are not independent,Use the *-operator to detach a parameter from a list or tuple when the function is called:>>>Range(36# Normal call with separate arguments[3, 4, 5][36]range( *args# arguments unpacked from a list[3, 4, 5] In the same way, you can use the * *-operation Foujian dictionary to pass the keyword parameters:>>>>>>DefParrot(Voltage,State=' A stiff ',Action=' Voom '):...Print"--this

But in 2.6, the official document (https://docs.python.org/2.6/whatsnew/2.6.html) clearly states that "there are some important new software packages added to standard libraries, such as multiprocessing and json, but compared with python 3, 2.6 of these packages will not introduce more new features. "Therefore, if you install Python or a later version of shoes, you do not need to download the json package. you can directly import the json package as needed. in the Lib under the inst

smallest bird of prey: Bozhan, with a length of 150 cm and a weight of 35 grams. Birds with the most feathers: Swan, more than 25000. Birds with the least feathers: Hummingbird, less than 1000. Longest feather bird: The Paradise is Lili, and the tail feathers are more than twice the length. Longest-lived bird: There are many longevity birds. For example, the average life cycle of a large sea bread is 50 ~ In 60 years, large parrots will survive around 100. In Liverpo

shoes, you do not need to download the json package. You can directly import the json package as needed. In the Lib under the installation directory, see the two packages (Click here to read the source code carefully, there will be more gains,) as shown in the following article: Python and later versions support Json encoding and decoding, and most built-in python types and Json conversion. The simplest example is as follows: >>> import json>>> data = {"spam" : "foo", "
