How to make an algorithm more concise

def figure_filter (self, url): 

index = 0
end_figure = re.findall("[^/]+(?!.*/)", url)
if end_figure:
    all_figure = re.findall("\d+", end_figure[0])
    for each_figure in all_figure:
        if len(each_figure) < 5:
            index += 1
    if index == len(all_figure):
        return url

the counter I use here is to calculate a regular match of all numbers less than 5 and return this url, but I use an index count, is there a more concise way to write

although not python, you can fix
with regular matching [5-9] + if it succeeds, there is a number > = 5
if it fails, return URL

the method of @ Fractal upstairs is feasible.
all digits whose length is less than 5 are returned equivalent to only one or more digits whose length is greater than 5 are not returned
the following is the supplementary python code 

import re
def figure_filter(url):
    end_figure = re.findall('[^/]+(?!.*/)', url)
    if end_figure:
        -sharp check if there is figure with length > 5
        long_figure = re.findall('\d{5,}', end_figure[0])
        if not long_figure:
            return url
        
print(figure_filter('http://www.12a123b123c.com')) -sharp http://www.12a123b123c.com
print(figure_filter('http://www.12a345678bc.com')) -sharp None

Next: Use Eloquent orm about the inconsistency between the PHP parameter type and the mysql field type, resulting in not going to the index, some thinking? I hope someone will solve the problem.
