also found in ``tools/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()
