title: Telegram Bot respond to specific command in Python list
body: <p>I am making a Telegram bot that can can access database to reply users' query. The bot need to respond to specific request of certain data in database. I was able to solve for when users request for all data but I am stuck with individual data. I am using <code>telegram.ext</code> from <code>telegram</code> package in python. Here is what I have done so far.</p>
  
  <pre><code>from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
  import MySQLdb
  
  currr = [] # global list var ~don't bash me for using global in python please, I'm a newbie
  
  # request for all data in database
  def request2(bot, update):
      db = MySQLdb.connect(host = "local", user = "root", passwd = "pwd", db = "mydb")
      cur = db.cursor()
      cur.execute("select ID from table")
      ID = cur.fetchall()
  
      cur.execute("SELECT ID, temp FROM table2 order by indexs desc")
      each_rows = cur.fetchall()
      for IDs in ID:
          for each_row in each_rows:
              if str(each_row[0])[0:4]==str(ID)[2:6]:
                  update.message.reply_text('reply all related data here')
                  break
  
  # request for single data
  def individualreq(bot, update):
      db = pymysql.connect(host = "localhost", user = "root", passwd = "pwd", db = "mydb")
      update.message.reply_text('reply individual data to users here')
  
  def main():
      updater = Updater("TOKEN")
      dp = updater.dispatcher
  
      global currr
      # get all ID form database
      db = MySQLdb.connect(host = "localhost", user = "root", passwd = "pwd", db = "mydb")
      cur = db.cursor()
      cur.execute("select ID from table")
      curr_ID = cur.fetchall()
  
      # example ID = 'F01', 'F02', 'F03'
      for curr_IDs in curr_ID:
          currr.append(curr_IDs[0])
  
      # request all data
      dp.add_handler(CommandHandler("all", request2))
  
      # request individual data
      dp.add_handler(CommandHandler(currr, individualreq)) # list command in currr[]
  
  if __name__ == '__main__':
      main()
  </code></pre>
  
  <p>I am looking for a way to pass the current command which is also the ID in database that user request in the <code>currr[]</code> list to the <code>individualreq(bot, update)</code> function so that only data of the called ID is being replied. Users will select from a list of ID in telegram and the command handler can pass the selected ID to the function. I have not found a way to pass the ID to the function. Could someone help me to solve this please. Thanks</p>
