input: Write a function to create a command-line application in Python that stores customer data and allows customers to query by customer name. The function should accept a customer name as an argument, search for the customer data, and print the results. If the application is run with invalid arguments, it should print an error message.
  
  assert print_customer_data("John Doe") == ("Customer ID: 12345", "Address: 123 Main St")
  assert print_customer_data("Jane Smith") == ("Customer ID: 67890", "Address: 456 Elm St")
  assert print_customer_data("Invalid Customer") == "Customer not found"
  
  def print_customer_data(name):
      # Code for searching customer data by customer name and printing results
      ...
  
  # Main function for the customer search application
  if __name__=="__main__":
      # Get command line arguments
      args = sys.argv
      
      if len(args) == 2:
          name = args[1]
          print_customer_data(name)
      else:
          print("Invalid arguments, please specify a customer name.")
output: def print_customer_data(name):
      customers = {
          "John Doe": ("Customer ID: 12345", "Address: 123 Main St"),
          "Jane Smith": ("Customer ID: 67890", "Address: 456 Elm St")
      }
      if name in customers:
          print(customers[name][0])
          print(customers[name][1])
      else:
          print("Customer not found")
