how can i know how many episode of a movie do i have in my file

i wanna know how many episode of a movie i have in my file.
the name of episodes are something like this:
"name.S01E01.720p.WEB-DL.mkv", "name.S01E02..."
i think i should use something like this but idk what's next

import os
with os.scandir(path) as files:
    for file in files:
    ...

but every movie has a specific name (for example)"name.Joint.Economic.Area.S01E01.720p.NF.WEBRip.x264-GalaxyTV" or some thing else and i wanna write a code that would work with any kind of names

i think the way that im doing this is not a professional way to do it.

i used this one:

import os
with os.scandir(path) as files:
    for file in files:
        num = 01
        if any(str(num) in file.name):
            print("yes")

but i got an error.

maybe this can help:

#!/usr/bin/env python3
import glob
import os,sys
import re
import json
try:
  movie_path_orig = sys.argv[1]
except:
  print(f"use ./{sys.argv[0]} <movie path>")
  sys.exit(0)

movie_path = os.path.join(movie_path_orig, "*.mkv")

print(f"Processing {movie_path}..")
files = glob.glob(movie_path)

summary = {}
for f in files:
  r=re.search("^(.*)S([0-9]{2})E([0-9]{2})(.*)", f)
  prefix = r.group(1)
  s = int(r.group(2)) #season
  e = int(r.group(3)) #episode
  suffix = r.group(4)
  if prefix not in summary.keys():
    summary[prefix] = { 'seasons': { f"{s}": e }, 'prefix': prefix, 'suffix': suffix}
  else:
    if f"{s}" not in summary[prefix]['seasons'].keys():
       summary[prefix]['seasons'][f"{s}"] = e
    else:
       summary[prefix]['seasons'][f"{s}"] = max(summary[prefix]['seasons'][f"{s}"], e)

print(json.dumps(summary, sort_keys=True, indent=4))

for i in summary.keys():
  for season in summary[i]['seasons'].keys():
    for episode in range(1, summary[i]['seasons'][season]+1):
      s = "{:02d}".format(int(season))
      e = "{:02d}".format(episode)
      file2chk = f"{summary[i]['prefix']}S{s}E{e}{summary[i]['suffix']}"
      if not os.path.exists(file2chk):
          print(f"missing {file2chk}")

first, you need to know the last episode of each season for each movie (first for), then check for everything starting from episode 01 (second for). Just make sure you have the last episode.

for a movie dir with:

name.Joint.Economic.Area.S01E01.720p.NF.WEBRip.x264-GalaxyTV.mkv
name.Joint.Economic.Area.S02E03.720p.NF.WEBRip.x264-GalaxyTV.mkv

it outputs:

Processing movies/*.mkv..
{
"movies/name.Joint.Economic.Area.": {
"prefix": "movies/name.Joint.Economic.Area.",
"seasons": {
"1": 1,
"2": 3
},
"suffix": ".720p.NF.WEBRip.x264-GalaxyTV.mkv"
}
}
missing movies/name.Joint.Economic.Area.S02E01.720p.NF.WEBRip.x264-GalaxyTV.mkv
