Description
Totpy is CLI TOTP generator and management tool for Linux and MacOS. Can generate a TOTP token from a given secret key or from one stored in the configuration file. The secrets can be added to the configuration file using a secret key or the QR code image of a secret key. The default configuration file is stored in ~/.local/config/totpy, but can be overriden with a given one.

$ totpy -a foo -q foo.png
Or passing directly the secret using the -s option:
$ totpy -a foo -s JBSWY3DPEHPK3PXP
If the entry already exists it will be overwriten.

Totpy module
Totpy includes three classes:

Base: A helper class for managing the configuration file.
Totpy: The class that defines the totpy CLI tool behaviour.
Totp: The class that generates the token.

Totp class
This can be imported in your project and used. This is the source code:
class Totp(object):
"""docstring for Totpy"""
def __init__(self, secret):
self.secret = secret

def getHotpToken(self, interval):
key = base64.b32decode(self.secret, True)
msg = struct.pack(">Q", int(time.time()) // interval)
h = hmac.new(key, msg, hashlib.sha1).digest()
o = h[19] & 15
h = (struct.unpack(">I", h[o:o+4])[0] & 0x7fffffff) % 1000000
return h

def getTotpToken(self):
return self.getHotpToken(interval=30)
