also found in ``helloworld.py``

.. code:: python

  #!/usr/bin/env python

  from trezorlib.client import TrezorClient
  from trezorlib.transport_hid import HidTransport

  def main():
      # List all connected TREZORs on USB
      devices = HidTransport.enumerate()

      # Check whether we found any
      if len(devices) == 0:
          print 'No TREZOR found'
          return

      # Use first connected device
      transport = HidTransport(devices[0])

      # Creates object for manipulating TREZOR
      client = TrezorClient(transport)

      # Print out TREZOR's features and settings
      print client.features

      # Get the first address of first BIP44 account
      # (should be the same address as shown in mytrezor.com)
      bip32_path = client.expand_path("44'/0'/0'/0/0")
      address = client.get_address('Bitcoin', bip32_path)
      print 'Bitcoin address:', address

      client.close()

  if __name__ == '__main__':
      main()

PIN Entering
------------

When you are asked for PIN, you have to enter scrambled PIN. Follow the numbers shown on TREZOR display and enter the their positions using the numeric keyboard mapping:

=== === ===
 7   8   9
 4   5   6
 1   2   3
=== === ===
