I try use python-telegram-bot

I do not understand how to handle InlineKeyboardButton correctly.

def start(bot, update):

    currencies = [currency for currency in API().get_currencies()]    

    keyboard = [[InlineKeyboardButton("{}".format(c), callback_data='{}'.format(c))] for c in currencies]

    reply_markup = InlineKeyboardMarkup(keyboard)

    update.message.reply_text('Select the currency you want to exchange:', reply_markup=reply_markup)


updater.dispatcher.add_handler(CommandHandler('start', start))

Now, I need to process the selection by passing it to another function with the help of ChosenInlineResultHandler, but I do not understand how to do this.

You are using Inline Buttons and the query coming back is simply CallbackQuery but not InlineQuery, yes the names are a bit confusing by the Telegram Bot API.

You can use telegram.ext.CallbackQueryHandler to catch the queries upon buttons pressed.

def button_callback(bot, update):
    # data is the callback_data where you declared in the buttons
    query = update.callback_query.data
    if query == "something":
        # do something here

updater.dispatcher.add_handler(CallbackQueryHandler(button_callback))

This is a minimal example of how to catch the buttons' data. You can check here for a complete example.
