Issue with script to delete the files with particular extension

I have written the following script to delete the files with a particular extension.However, this script delete the file with the extension '.log' or '.txt' or '.css'.

What if the file extension is '.log000123' or '.log1234', so here extension is constant but random numbers are added after the extension. What can be done to delete such files as well through this script?

Any modification in the script or link to any website where such example is covered will be appreciated. 

import os, time, sys

folder_path = "C:\SampleFolder"
file_ends_with = ".log"
how_many_days_old_logs_to_remove = 7

now = time.time()
only_files = []

for file in os.listdir(folder_path):
    file_full_path = os.path.join(folder_path,file)
    if os.path.isfile(file_full_path) and file.endswith(file_ends_with):
        #Delete files older than x days
        if os.stat(file_full_path).st_mtime < now - how_many_days_old_logs_to_remove * 86400: 
             os.remove(file_full_path)
             print "\n File Removed : " , file_full_path

We could use Regular expressions to determine if the file is a log file.

Rather than using time module you could use datetime module if your sole intention is to delete the log files that are older than 7 days.

Have a look at code below:

import re
import datetime
import os

folder_path = "C:\SampleFolder"
only_files = []

for file in os.listdir(folder_path):
    file_full_path = os.path.join(folder_path, file)
    if os.path.isfile(file_full_path) and re.search(r".*\.log.*", file_full_path):
        # Delete files older than x days
        last_mod_time = datetime.datetime.fromtimestamp(os.stat(file_full_path).st_mtime)
        limt_mod_time = datetime.datetime.today() - datetime.timedelta(days=7)

        if last_mod_time < limt_mod_time:
            os.remove(file_full_path)
            print("\n File Removed : ", file_full_path)

Try this :

import fnmatch
import os

matches = []
folder_path = "C:\SampleFolder"

how_many_days_old_logs_to_remove = 7

now = time.time()

for root, dirnames, filenames in os.walk(folder_path):

    for filename in fnmatch.filter(filenames, '*.log*'):

        if os.stat(filename).st_mtime < now - how_many_days_old_logs_to_remove * 86400: 
             os.remove(filename)
             print "\n File Removed : " , file_full_path

        # matches.append(os.path.join(root, filename))

You can use regular expressions and os.path.splitext:

import os
import re

file = "myfile.log123"

pattern = ".log(.*)"  # match .log followed by anything
fname, ext = os.path.splitext(file)

# check this condition:
if re.match(pattern, ext):
    # do stuff

This should work:

import os, time, sys

folder_path = "C:\SampleFolder"
file_contains = ".log"
how_many_days_old_logs_to_remove = 7

now = time.time()
only_files = []

for file in os.listdir(folder_path):
    file_full_path = os.path.join(folder_path,file)
    if os.path.isfile(file_full_path) and file_contains in file_full_path:
        #Delete files older than x days
        if os.stat(file_full_path).st_mtime < now - how_many_days_old_logs_to_remove * 86400: 
             os.remove(file_full_path)
             print "\n File Removed : " , file_full_path
