Python Telegram Bot Edit Custom Keyboard

I am using the Python Telegram BOT API for building a demo application. The task I am trying to achieve is to create a custom keyboard and then keep editing the keyboard keys upon each interaction with the user. I tried using "edit_message_reply_markup" but I get an error "Message Can't be edited". Is it not possible to edit a custom keyboard?

Here is the sample code that I have written for my task.

Initial Task:

FirstKeyboard = [[KeyboardButton(text = "FRUITS"), KeyboardButton(text = "VEGITABLES"), KeyboardButton(text = "DRINKS")],[KeyboardButton(text = "SNACKS"), KeyboardButton(text = "CHIPS"), KeyboardButton(text = "NOTHING")],[KeyboardButton(text = "DONE")]]
menu = ReplyKeyboardMarkup(FirstKeyboard)
KeyboardMessageID = context.bot.send_message(chat_id = chatID, text = "Select What you Like", reply_markup = menu)

Edit Task:

SecondKeyBoard = [[KeyboardButton(text = "APPLE"), KeyboardButton(text = "BANANA"), KeyboardButton(text = "PUMPKIN")],[KeyboardButton(text = "ORANGES"), KeyboardButton(text = "GRAPES"), KeyboardButton(text = "WINE")],[KeyboardButton(text = "DONE")]]
menu = ReplyKeyboardMarkup(SecondKeyBoard)
KeyboardMessageID = context.bot.edit_message_reply_markup(chat_id = chatID, message_id = KeyboardMessageID, reply_markup = menu)

I get an Error "Message can't be edited"

use context.message.reply_text("your text", reply_markup=your key board markups). and be sure that at least one of text or markup changed then you got error for same input. - mujad

You can send a new message with new KeyboardButton instead of editing previous message. New ReplyKeyboardMarkup will be replaced with the old ReplyKeyboardMarkup automatically. using:

context.bot.send_message(chat_id = chatID, text = "Select What you 
Like", reply_markup = NEW_Menu)

or reply to your user with:

update.message.reply_text(text = "Select What you Like", reply_markup = NEW_Menu)

You can change your text in the new massage or put it as the previous one.

Looks like at the moment we can edit inline keyboards, and can't edit reply keyboards

As a workaround I delete previous message and dublicate it except reply_markup parameter. In your case something like:

context.user_data['last_message'] = context.bot.send_message(chat_id = chatID, text = "Select What you Like", reply_markup = menu)

# changing reply markup
last_message = context.user_data['last_message']
context.bot.delete_message(chat_id=update.effective_chat.id, message_id=last_message.message_id)
# create similar message except new menu
context.user_data['last_message'] = context.bot.send_message(chat_id = last_message.chat_id, text = last_message.text, reply_markup = new_menu)
