I am currently using Beautiful Soup to parse an HTML file and calling get_text(), but it seems like I’m being left with a lot of \xa0 Unicode representing spaces. Is there an efficient way to remove all of them in Python 2.7, and change them into spaces? I guess the more generalized question would be, is … Read more

Well I can see two solutions here: 1) Follow the Docs-Tkinter install for Python (for Windows): Tkinter (and, since Python 3.1, ttk) are included with all standard Python distributions. It is important that you use a version of Python supporting Tk 8.5 or greater, and ttk. We recommend installing the “ActivePython” distribution from ActiveState, which includes everything … Read more
np.arange(2) gives array([0, 1]), so only two values. If you try to plot three values (in y1 or y2) against this, that won’t work and it will throw the ValueError (telling you exactly this): Try using np.arange(3).
