How to import and use a module with one line

Question

I have this code that loads the natural gas storage numbers from the internet.

from urllib.request import urlopen
print(int(str(urlopen("http://ir.eia.gov/ngs/wngsr.txt").read()).split("\n")[4].split(" ")[2]))

How could I do this in one line? More specifically, I was wondering how I could get rid of the import line and do something like this:

print(int(str(urllib.request.urlopen("http://ir.eia.gov/ngs/wngsr.txt").read()).split("\n")[4].split(" ")[2]))

(I changed the urlopen call to urllib.request.urlopen. It would be sort of like Java, if you use the fully qualified name, you don’t need an import statement.)

You always need the import, however you can still use semi-colons to separate statements:

from urllib.request import urlopen; print(int(str(urllib.request.urlopen("http://ir.eia.gov/ngs/wngsr.txt").read()).split("\n")[4].split(" ")[2]))
#             note the semi-colon ^

When trying out the suggestion by Zizouz212, I found this works

print(int(str(__import__('urllib').request.urlopen("http://ir.eia.gov/ngs/wngsr.txt").read()).split("\n")[4].split(" ")[2]))
