Commentary

urllib2 urllib2 is a python module that gets resources on the net from URLs.

import urllib2
response = urllib2.urlopen('http://python.org/')
html = response.read()

Reference: http://docs.python.jp/2/howto/urllib2.html

In this code,

resp = urllib2.urlopen('http://weather.livedoor.com/forecast/webservice/json/v1?city=%s'%citycode).read()

That's right. Here, we are getting resources from the api of "http://weather.livedoor.com".

sys.argv sys defines functions that are closely related to the operation of the interpreter.

Interpreter: An interpreter is software that executes a program while converting a software design drawing (source code) written in a programming language by a human into a computer-executable format (object code). Interpreter-type languages are slower than compiler-type languages because they are converted when the program is executed. Source: [IT terminology e-Words | Interpreter](http://e-words.jp/w/%E3%82%A4%E3%83%B3%E3%82%BF%E3%83%97 % E3% 83% AA% E3% 82% BF.html)

Especially here, we use sys.argv. This allows you to receive arguments from the command line. Since argv [0] `` `receives the script name, this code uses the first argument argv [1] `` `.

try, except try and except handle error handling. If no exception occurs in the try clause, the except clause is skipped. If an exception occurs, execute the except clause.

This time, if there is a command line argument, give that code to citycode, otherwise give Kagoshima's code to citycode. Reference: 8. Errors and Exceptions

json I'm using a json module to decode the retrieved json.

json.loads()

This time, the received data is converted from json type to dictionary type. 18.2. json — JSON encoder and decoder
