title: Stuck in an error where the app is not accepting input
body: <p>So I am doing an assignment for my university for making a simple catering system on python. The part of the code where the issue is:</p>
  
  <pre><code>def other_services():
      global servicesCart
      services = [{"name":"1. Tent per 10 feet","price":400},{"name":"2. Chairs per 50 peices","price":50},{"name":"3. Tables per 10 pieces","price":80},{"name":"4. Table cloth per 10 peices","price":20}]
      print("Press E to exit")
      while True:
          for f in services:
              print("Name : ",f['name'],"Price : ",str(f['price']))
          selectedService = input("give your order")
          if (selectedService == "E"):
              cms()
          try:
              servicesCart.append(food_lunch[int(selectedService) - 1]) * (people)
          except:
              print("Wrong input, please try again.")}
  </code></pre>
  
  <p>The issue is that no matter what input I give, the output remains wrong input, please try again. The people in this is the number of guests that is asked in the beginning of the code and has an integer value. Any help will be greatly helpful. Thank you.</p>
