This week, I wanted to refresh my memory and get back into programming . I fold a group on meetup called ‘Girl Develop it NYC’ which is a women coding group. They were founded in 2010 and they goal is to teach women how to code .  Today we are learning Numpy ,which is a open source python package for scientific computing .Numpy is used for data science, research, finance and data analysis. Our instructor today Vivian Lam , she was really helpful .
