• What is this?

  Professor I know this is not a correct Tutorial Tag for the Doubt I am asking. It is regarding Installation sheet. There no error occurred in the command prompt. Just these lines occurring which is somewhat not similar to what you have written in the last paragraph as  "NOTE:" in that sheet. What should I do? Is everything correct here in installation process or have I committed some mistake?Matplotlib is building the font cache; this may take a moment.Installed tk event loop hook.Shell is already running a gui event loop for tk. Call with no arguments to disable the current loop.Using matplotlib backend: TkAgg%pylab is deprecated, use %matplotlib inline and import the required libraries.Populating the interactive namespace from numpy and matplotlib

Maybe that is causing the error, but not sure. please help with this.

• Solution to Exercise 2. Is is correct?

    I have tried the exercise 2 question as follows:  S = [0.19, 0.38, 0.57, 0.77, 0.96, 1.15, 1.34, 1.54, 1.73]  n = [10.74, 14.01, 18.52, 20.23, 22.88, 24.59, 27.55, 28.48, 30.20]  delta_S = [0.006, 0.006, 0.005, 0.003, 0.004, 0.007, 0.004, 0.004, 0.007]  delta_n = [0.61, 0.69, 0.53, 0.38, 0.46, 0.37, 0.46, 0.46, 0.37]  nsquare = square(n)  Plot 1:  plot(S,n,'.')  errorbar(S, n, xerr = delta_S, yerr = delta_n, fmt = 'bo')  Each point is of the form:   Similarly Plot2:  plot(S,nsquare,'.')  errorbar(S, nsquare, xerr = delta_S, yerr = delta_n, fmt = 'bo')  Here we have to zoom a lot more to see the error in the measurement data.  Kindly comment whether it is correct or not.
