  We faced 2 issues :1. cat command is specific to unix (linux). It does not work on windows. But certain commands such as pwd ( print working directory )    works on windows. I have installed Python & IPython on my Windows 7 ( Professional )2. The last question the answer is not correct. The question is "Given a file data.txt with 3 columns of data separated by spaces, read      into 3 separate simple sequences. The answer in the video is :     x = loadtxt("data.txt", unpack = True, delimiter=":")    Answer should be =>    x, y, z = loadtxt("data.txt", unpack=True, delimiter=":")3.
