When i ran the fierce --domain and the website name then first it was running successfully but then it gave me errors in python code and the following is the result that has shown
fierce --domain unitycodemonkey.com

TypeError: 'float' object cannot be interpreted as an integer

so now it is a big error i have not tried the other options of the fierce so fix this issue.
