Hi, I would like someone that is good in Python to complete 3 easy Python exercises 15 minutes/each. There are Linear Regression, Multilinear Regression and Logistic Regression exercises, with sklearn and matplotlib, pandas,pylab, numpy libraries. The exercises have examples above, so this is a simple copy-paste procedure for someone that knows Python in the mentioned fields. The right candidate doesn't need more than an hour.
