I suggest for start create a good portfolio in Upwork(former Elanse,Odesk) and search for offers with limit you Skills and Languages. Python is just langugage, you should focus on area: machine learning, web developer (easy one) and etc.
If you set rate 10$/hr or less, probably you find offer for few weeks/month work in same week. It helps to earn XP and portfolio. Then increase rate, depends on current market.
