Calling one method from another within same class in Python

Question

I am very new to python  I was trying to pass value from one method to another within the class  I searched about the issue but i could not get proper solution  Because in my code   if  is calling class s method  on any event  that in return should call my another method  dropbox fn   which make use of the value from  on any event   Will it work  if the  dropbox fn  method is outside the class   I will illustrate with code    class MyHandler FileSystemEventHandler    def on any event self  event       srcpath event src path     print  srcpath   has been   event event type      print  datetime datetime now         print srcpath split      12        filename srcpath 12       return filename   I tried to call the method  showed error like not callable    def dropbox fn self   Or will it work if this methos is outside the class        this method uses  filename   if   name         main       path   sys argv 1  if len sys argv   gt  1 else       print   entry     event handler   MyHandler     observer   Observer     observer schedule event handler  path  recursive True    observer start     try       while True           time sleep 1    except KeyboardInterrupt      observer stop     observer join     The main issue in here is   I cannot call  on any event  method without event parameter  So rather than returning value  calling  dropbox fn  inside  on any event  would be a better way  Can someone help with this

To call the method  you need to qualify function with self   In addition to that  if you want to pass a filename  add a filename parameter  or other name you want    class MyHandler FileSystemEventHandler        def on any event self  event           srcpath   event src path         print  srcpath   has been   event event type          print  datetime datetime now            filename   srcpath 12           self dropbox fn filename     lt ----      def dropbox fn self  filename       lt -----         print  In dropbox fn    filename

To accessing member functions or variables from one scope to another scope  In your case one method to another method we need to refer method or variable with class object  and you can do it by referring with self keyword which refer as class object     class YourClass         def your function self   args            self callable function param    if you need to pass any parameter      def callable function self   params            print  Your param    param
