error observed in Python 2.7.17 and Python 3.6.9 and works fine with Python 2.7.12

Traceback (most recent call last):
File "lb.py", line 3, in
from haproxystats import HAProxyServer
ImportError: cannot import name HAProxyServer

I am getting an error "No handlers could be found for logger "haproxystats"" if I run below commands:

from haproxystats import HAProxyServer
haproxy = HAProxyServer('192.168.122.215:9001')
for b in haproxy.backends:
print('%s: %s' % (b.name, b.status))
I have stored above commands in one file and kept it in a same folder where HAProxy server resides. When I run these commands, I am getting an error(specified above).

Can you please check it once and tell me where am I going wrong?

Thanks.

In README.md

hs = HaproxyStats(base_urls,user='<username>',user_pass='<password>')

but correct version i think is

hs = HaproxyStats(base_urls,user='<username>',password='<password>')
