I have a long url pattern in Django similar to this:
url(r'^(?i)top-dir/(?P<first_slug>[-\w]+?)/(?P<second_slug>[-\w]+?)/(?P<third_slug>[-\w]+?).html/$',
'apps.Discussion.views.pricing',
Definitely it doesn't follow PEP8 guide as the characters are more than 80 in a single line. I have found two approach of solving this:
The first one (using backslash):
url(r'^(?i)top-dir/(?P<first_slug>[-\w]+?)/(?P<second_slug>[-\w]+?)'\
'/(?P<third_slug>[-\w]+?).html/$',
'apps.Discussion.views.pricing',
The second one - using ():
url((r'^(?i)top-dir/(?P<first_slug>[-\w]+?)/(?P<second_slug>[-\w]+?)',
r'/(?P<third_slug>[-\w]+?).html/$'),
'apps.Discussion.views.pricing'),
Both of them break by Regex. Is there a better approach to solve this issue. OR Is it a bad practice to write such long Regex for urls.

A URL pattern is a set of ordered characters to which the Google Search Appliance matches actual URLs that the crawler discovers. You can specify URL patterns for which your index should include matching URLs and URL patterns for which your index should exclude matching URLs.
VERBOSE. This flag allows you to write regular expressions that look nicer and are more readable by allowing you to visually separate logical sections of the pattern and add comments.
A RegEx, or Regular Expression, is a sequence of characters that forms a search pattern. RegEx can be used to check if a string contains the specified search pattern.
Adjacent strings are concatenated, so you can do something like this:
url(r'^(?i)top-dir/(?P<first_slug>[-\w]+?)/'
r'(?P<second_slug>[-\w]+?)/'
r'(?P<third_slug>[-\w]+?).html/$',
'apps.Discussion.views.pricing',)
