How much python do i need to know before starting on AI? • r/artificial

Python is a new language for me and I've learnt it (reasonably) only for trying out AI...I ve strong base in Math and stuff.. so python is the only thing keeping me from going ahead with AI...I learnt python from " Learn Python the hard way" by zed Shaw...And comfortable with that is taught in the book...loops, Functions, classes, lists etc...Now my confusion is what to do next...Shud I continue learning python and try AI only after mastering python...Or shall I go ahead with AI and develop my python skills as I go along... I've decided to take AI course from edx by ColombiaX....It's based on Python.. Any suggestions (or resources) will be very helpful...Thanx in advance
