Plotting a histogram and normal distribution - easy example for Python and Matlab/Octave

I was looking for a way to automate statistics used in physics practical experiments calculating the mean, standard deviation and errors and plotting the histogram, normalized histogram and normal distribution. I have examples of the program in both Matlab and Python in the link below. I added a file for using Sturge's rule to structure data (figure 2) as well as an example of the problem with unstructured data (figure 1).

If you know of a better or easier way to do this - please let me know.
