from flask import Flask,send_file
import os

# this lib will reload custom functions after every change
# hence no need to restart server after every change
import importlib

# custom functions
import functions

# flask root object
app=Flask(__name__)

# handles requests for index page
@app.route('/')
def index():
  importlib.reload(functions)
  return functions.index()

# when change directory (cd) is required
@app.route('/change_page',methods=['POST'])
def change_page():
  importlib.reload(functions)
  return functions.change_page()

# to handle terminal commands
@app.route('/execute_command',methods=['POST'])
def execute_command():
  importlib.reload(functions)
  return functions.execute_command()

# to serve files other than index page
@app.route('/',methods=['GET'])
def requested_files(filename):
  importlib.reload(functions)
  # to edit any file in text editor
  if filename == "file.html":
    return functions.files()
  # favion icon
  elif filename == "favicon.ico":
    return "" # not required so just returning an empty string
  # terminal UI page
  elif filename == "terminal.html": 
    return functions.terminal_page()
  # other files from directory like png,mp4 etc
  else:
    return send_file(filename)

if __name__=="__main__":
  # uncomment only for development debbuging
  # app.config['DEBUG']=True

  # runs server @ localhost
  app.run(host="127.0.0.1",port=5000)

  #runs server at wlan network can be accesible with other devices
  # app.run(host="192.168.137.1",port=5000)

Module named functions contains helper functions

# return list of files and folder in directory
def serve_items():
  # python list of names
  title=os.getcwd()
  # we will items in group of 5 to arrange in a row
  dir_items = [[]]
  for x in os.listdir():
    # y will store absolute path of item
    y=os.path.join(title,x)
    # ext will store ext of item
    ext = x.lower().split(".",1)[-1]
    # if group is filled start new group of five items
    if len(dir_items[-1])==5:
      dir_items.append([])
    # if item is directory
    if os.path.isdir(x):
      dir_items[-1].append({'a':y,'n':x,'type':'folder'})
    # if item is a image
    elif ext in ["png","jpg"]:
      dir_items[-1].append({'a':y,'n':x,'type':'graphic',"ext":ext})
    # if item is a video
    elif ext in ["mp4","mkv","3gp"]:
      dir_items[-1].append({'a':y,'n':x,'type':'video',"ext":ext})
    # other files
    else:
      dir_items[-1].append({'a':y,'n':x,'type':'file'})

  return dir_items

def index():
  # return app.html page
  return render_template("explorer.html",title="file explorer",dir_items=serve_items())

def terminal_page():
  # return terminal UI page
  return render_template("terminal.html")

def change_page():
  # returns content of changed directory after cd
  cd = request.values.get("cd")
  os.chdir(cd)
  return render_template("serve_items.html",dir_items=serve_items())

def files():
  # return file editor page
  return render_template("file.html")

def execute_command():
