Have you actually tried reading the documentation? The _very_ first
section of the urllib documentation we have urllib.request.urlopen
[1]. Which looks to me what you are looking for as a replacement to
urllib2.urlopen().
Some *untested* inline comments below.

a =
request.urlopen('http://www.marketwatch.com/investing/currency/CUR_USDYEN').read(20500)

> print rate
print(rate)
Also http://docs.python.org/library/2to3.html discusses the automated
tool for converting python code.
