To save a webpage to a file:
-------------------------------------
1. import urllib
2. urllib.urlretrieve("http://econpy.pythonanywhere.com
/ex/001.html","D:\file.html")
-------------------------------------
Note, for paths on windows you really want to use a rawstring. Ie,
r"D:\file.html".
Thanks.
I actually use "D:\\file.html" in my code.
Or you can do that. But the whole point of raw strings is not having to
escape slashes :)
Trying the rawstring thing (say it fast 3x):
webpage = "http://econpy.pythonanywhere.com/ex/001.html";
----------------------------------------------------
webfile = "D:\\econpy001.html"
urllib.urlretrieve(webpage,webfile) WORKS
----------------------------------------------------
webfile = "rD:\econpy001.html"
urllib.urlretrieve(webpage,webfile) FAILS
----------------------------------------------------
webfile = "D:\econpy001.html"
urllib.urlretrieve(webpage,"r" + webfile) FAILS
----------------------------------------------------
webfile = "D:\econpy001.html"
urllib.urlretrieve(webpage,"r" + "" + webfile + "") FAILS
----------------------------------------------------
The FAILs throw:
Traceback (most recent call last):
File "webscraper.py", line 54, in <module>

File "D:\development\python\python_2.7.11\lib\urllib.py", line 98, in

return opener.retrieve(url, filename, reporthook, data)
File "D:\development\python\python_2.7.11\lib\urllib.py", line 249,
in retrieve
tfp = open(filename, 'wb')
IOError: [Errno 22] invalid mode ('wb') or filename: 'rD:\\econpy001.html'
----------------------------------------------------
What am I doing wrong?
