Run the code to test it. Obviously, you need to be connected to the Internet for it to work.
The program should print the latest tweets that contain the word
chicken.
Press Ctrl + C to
stop the program.
You are nearly ready to add in the code that controls the toy, but before you do, it is worth
looking at how the code works.
By now you should be recognising statements in the program. First you import three mod-
ules that you need. The Time module provides the
sleep()
function that creates the delay
between each time you check Twitter. The Sys module provides a way to get command-line
arguments. Next constants are defined before the main function begins.
The Twitter module is written in OOP style, so you create an
api
object with the following
statement:
api = twitter.Api(consumer_key='xxxxxxcxK9I3g',
↵
consumer_secret='xxxxxfLBmh0gqHohRdkEH891B2XCv00',
↵
access_token_key='xxxxx25-
↵
Dw8foMCfNec2Gff72qxxxxxwMwomXYo',
↵
access_token_secret='xxxxxxjIuFb88dI')
