"""A Python 3 script to write a file with a specified number """A Python 3 script to write a file with a specified number
of keypairs, using bigchaindb.crypto.generate_key_pair() of keypairs, using bigchaindb.crypto.generate_key_pair()
The file is always named keypairs.py (and is Python 2). The file is always named keypairs.py and it should be interpreted
as a Python 3 script.
