How to solve this problem with regular expressions?

Question

Django

Greetings.
There is a urls.py file

urlpatterns = [
    ...
    url(r'^last/', last_images, name='last_images'),
    url(r'(?P<slug>[-\w]+)/$', show_image, name='show_image'),
    url(r'(?P<slug>[-\w]+)/delete/$', delete_image, name='delete_image'),

]

And the problem is that when you go to an address like /myimage/delete/ , the first regular expression fires and displays an error. How can I solve this problem?
Swapping them around doesn't seem like the right thing to do.
Thank you.

> Places to change them like it would not be entirely correct.
Why?
Swap them and don't fool around.

Answer 2

r'^last/'
r'^last/$'
