I'm trying to extract some zip files and after extractions reading only specific CSV files from this folder, there is one pattern but I couldnt place the code. The pattern is Im looking numeric name file, here is my code.

```
import glob
import pandas as pd
import zipfile
from os import listdir
from os.path import isfile, join

path = r'C:\Users\han\Desktop\Selenium'
all_files = glob.glob(path + "/*.zip")

li = []

for filename in all_files:
    with zipfile.ZipFile(filename, 'r') as zip_ref:
        zip_ref.extractall(r'C:\Users\han\Desktop\Selenium')

detail = [f for f in listdir(r'C:\Users\han\Desktop\Selenium\detail') if isfile(join(r'C:\Users\han.37\Desktop\Selenium\detail', f))]

```

After this point, my detail list is like this

```
    ['119218.csv',
     '119218_coaching.csv',
     '119218_coaching_comment.csv',
     '119218_emp_monitor.csv',
     '119218_monitor_work_time.csv',
     '119218_reponse_text.csv',
     '119218_response.csv',
     '119219.csv',
]

```

What I want is that reading only numeric ones which are **119218** and **119219** .csv. and ofc `pd.concat`
because they are same shaped data tables.

Thanks in advance
