Another reference that I like a lot for people who already know a programming language and are trying to learn Python is "Python Essential Reference" by David Beazley. It gives a good understanding of how Python works, though it does not talk about numerical computing libraries. Gaël _

Hi M, I think what you describe can be summarized as the difference of a domain specific language (r) and a general purpose language (Python). Most of what you describe is related to namespaces - "one honking great" feature of python. Namespaces are less needed in r because r is domain s

Hi, along with all the great tips you received, perhaps you may find this useful: http://www.cert.org/flocon/2011/matlab-python-xref.pdf I know is not on-topic with your question, but I found it very useful when I start to use python (coming from R) So I thought it was worth to post it here.

Thank you all for the love! Sean, I think your recommendation is perfect! It covers everything, very concise, to the point. Sebastian, I will certainly invest time into that course when I have time. Nelle, I agree! And from what I read, thee head(), tail(), and data.frame() in Python actually ca

Hello, The concepts behind R and python are entirely different. Python is meant to be as explicit as possible, and uses the concepts of namespace which R doesn't. While it can seem that python code is more verbose, it is very clear when reading python code which functions come from which module an

Hi, C W, yeah I'd say that Python is a programming language with lots of packages for scientific computing, whereas R is more of a toolbox for stats. Thus, Python may be a bit weird at first for people who come from the R/stats field and are new to programming. Not sure if it is necessary to le

Hi Sebastian, I looked through your book. I think it is great if you already know Python, and looking to learn machine learning. For me, I have some sense of machine learning, but none of Python. Unlike R, which is specifically for statistics analysis. Python is broad! Maybe some expert here wi

Dear Scikit-learn, What are some good ways and resources to learn Python for data analysis? I am extremely frustrated using this thing. Everything comes after a dot! Why would you type the sam thing at the beginning of every line. It's not efficient. code 1: y_sin = np.sin(x) y_cos = np.cos(x)
