input: Write a function `print_customer_data` that searches for a customer by name and prints the corresponding customer data. The function should be used in a command-line application that takes a customer name as an argument and prints the customer data if found, or an error message if the name is not provided. If the script is run without the required argument, it should print "Invalid arguments, please specify a customer name."
  assert print_customer_data("John Doe") # Should print customer data for "John Doe"
  assert print_customer_data("Jane Smith") # Should print customer data for "Jane Smith"
  assert print_customer_data("") # Should print nothing as no customer name is provided
  assert print_customer_data("Invalid Name") # Should print nothing as customer data for "Invalid Name" does not exist
output: def print_customer_data(name):
      if not name:
          print("Invalid arguments, please specify a customer name.")
          return
      customers = {
          "John Doe": "Customer data for John Doe",
          "Jane Smith": "Customer data for Jane Smith"
      }
      if name in customers:
          print(customers[name])
      else:
          return
