Urllib2中的异常引发-Python

Question

I'm trying to use the following code to check whether a given site is online:

url_list = ["www.apple.com", "www.invalidurlname.com"]
for i in url_list:
    try:
        urllib2.urlopen(i, timeout = 1)
    except urllib2.URLError:
        print "fail"
    else:
        print "pass"

It should produce:

pass
fail

However when I run it I get the following error:

  File "scanpb.py", line 7
urllib2.urlopen("http://apple.com", timeout = 1)
      ^
IndentationError: expected an indented block

Where have I gone wrong? Thanks.

Answer 1

You mixed tabs and spaces (displaying tabs as tab and spaces as . :

tab try:
....tab urllib2.urlopen(i, timeout = 1)

Set your editor to either one, and use your editor's replace function to replace all occurences (you can match tabs with \\t in regex mode).
