Nobody knew why it was named so, or who lived there, but stories about it passed down through generations, giving it an aura of mystique. 2 | 3 | In 1902, the mansion was owned by Lord Harrington, a nobleman known for his extravagant parties. Guests from all over the region would flock to the Whispering House to be part of these grand events. With chandeliers hanging from the ceilings, intricate paintings adorning the walls, and golden cutlery laid out on the tables, the mansion was a symbol of opulence. 4 | 5 | However, as the years went by, Lord Harrington started to change. Those who met him spoke of a distant look in his eyes, as if he was constantly lost in thought. Soon, the parties stopped. The mansion, once lively, fell silent. 6 | 7 | One fateful night, the town folks saw a bright light emanating from the mansion. The next day, Lord Harrington was nowhere to be found. The Whispering House was deserted. As days turned into weeks and weeks into months, the stories began. People claimed to hear faint whispers coming from the mansion, especially on full moon nights. 8 | 9 | Catherine, an inquisitive journalist, had recently moved to Greensville. She was fascinated by the mansion's story and decided to investigate. With a notebook in hand, she approached the mansion one evening. 10 | 11 | The main gate creaked open. Inside, the once-beautiful garden was now overgrown with weeds. As Catherine stepped into the mansion, she felt a cold breeze. The grand hall, which once echoed with laughter and chatter, was now filled with an eerie silence. 12 | 13 | Catherine started exploring room by room. In the ballroom, she saw the remnants of the last party; glasses half-filled with wine and plates with morsels of food, now covered in a thick layer of dust. In Lord Harrington's study, books lay scattered everywhere, and a lone diary rested on the desk. 14 | 15 | Curiosity piqued, Catherine started reading the diary. The entries spoke of Lord Harrington's discovery of a mysterious artifact during his travels to Egypt. It was a pendant with a bright blue gemstone. According to local legends, the gemstone had magical powers that could grant wishes but at a great cost. 16 | 17 | As Catherine read on, she realized that Lord Harrington had started wearing the pendant constantly. He wrote of hearing voices, which grew louder with each passing day. The last entry was particularly chilling. It read, “The voices won't stop. They are demanding a price I cannot pay." -------------------------------------------------------------------------------- /Chapter_10/Exercises/learning_python.txt:

Installing matplotlib 13 | --- 14 | 15 | There are many different ways to install matplotlib to your system. In this section, I'll recommend one method for each operating system. If you'd like to see the kinds of visualizations you can make with matplotlib, see the official matplotlib [sample gallery](http://matplotlib.org/gallery.html). When you click a visualization in the gallery, you can see the code used to generate the plot. 16 | 17 | ### Checking if matplotlib is already installed 18 | 19 | First, check if matplotlib is already installed on your system: 20 | 21 | $ python 22 | >>> import matplotlib 23 | >>> 24 | 25 | If you don't see an error message, then matplotlib is already installed on your system and you should be able to get started right away on this chapter's projects. If you get an error message, read the appropriate section below for help installing matplotlib on your operating system. 26 | 27 | Installing matplotlib on Linux 28 | --- 29 | 30 | If you're using the version of Python that came with your system, you can use your system's package manager to install matplotlib in one line. For Python 3, this is: 31 | 32 | $ sudo apt-get install python3-matplotlib 33 | 34 | If you're using Python 2.7, this is: 35 | 36 | $ sudo apt-get install python-matplotlib 37 | 38 | If you installed a newer version of Python, you'll have to install several libraries that matplotlib depends on: 39 | 40 | $ sudo apt-get install python3.5-dev python3.5-tk tk-dev 41 | $ sudo apt-get install libfreetype6-dev g++ 42 | 43 | Then use pip to install matplotlib: 44 | 45 | $ pip install --user matplotlib 46 | 47 | If you need help using pip, see the instructions in Chapter 12. 48 | 49 | [top](#) 50 | 51 | Installing matplotlib on OS X 52 | --- 53 | 54 | Aple includes matplotlib with its standard Python installation, so make sure you check if it's already installed before installing it yourself. 55 | 56 | If matplotlib is not already installed and you used Homebrew to install Python, install it like this: 57 | 58 | $ pip install --user matplotlib 59 | 60 | If you need help using pip, see the instructions in Chapter 12. If you have trouble installing matplotlib using pip, try leaving off the `--user` flag. 61 | 62 | [top](#) 63 | 64 | Installing matplotlib on Windows 65 | --- 66 | 67 | To install matplotlib on Windows you'll first need to install Visual Studio, which will help your system install the packages that matplotlib depends on. Go to [https://dev.windows.com/](https://dev.windows.com/), click [**Downloads**](https://dev.windows.com/downloads), and look for *Visual Studio Community*. This is a free set of developer tools for Windows. Download and run the installer. 68 | 69 | Next you'll need an installer for matplotlib. Go to [https://pypi.python.org/pypi/matplotlib/](https://pypi.python.org/pypi/matplotlib/) and look for a wheel file (a file ending in *.whl*) that matches the version of Python you’re using. For example, if you’re using a 32-bit version of Python 3.5, you’ll need to download *matplotlib-1.4.3-cp35-none-win32.whl*. 70 | 71 | If you don't see a file matching your installed version of Python, look at what’s available at [http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib](http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib). This site tends to release installers a little earlier than the official matplotlib site. 72 | 73 | Copy the *.whl* file to your project folder, open a command window, and navigate to the project folder. Then use pip to install matplotlib: 74 | 75 | > cd python_work 76 | python_work> python -m pip install --user matplotlib-1.4.3-cp35-none-win32.whl 77 | 78 | If you need help using pip, see the instructions in Chapter 12. 79 | 80 | [top](#) 81 | 82 | Installing Pygal 83 | --- 84 | Pygal has been updated recently, which is a good thing; you're learning a library that's being steadily improved. This also means you have two choices about how to install Pygal. You can install version 1.7 which supports the code in the book exactly as it's written, or you can install the most recent version of Pygal and modify some of the code in the book. If you install the most recent version there are some slight changes you'll need to make for the code in the second half of chapters 15 and 16, and chapter 17. 85 | 86 | ### Running Pygal code exactly as it appears in the book 87 | 88 | Pygal 1.7 allows the code to run exactly as it appears in the book. To do this, modify the command for installing pygal so pip will install version 1.7 (page 340): 89 | 90 | $ pip install --user pygal==1.7 91 | 92 | On Windows, this would be: 93 | 94 | > python -m pip install --user pygal==1.7 95 | 96 | If you've already installed Pygal you can see which version was installed by running the command `pip freeze`: 97 | 98 | $ pip freeze 99 | pygal==2.1.1 100 | 101 | If you installed Pygal 2.0 or later and want to install 1.7 instead, uninstall Pygal first: 102 | 103 | $ pip uninstall pygal 104 | $ pip install --user pygal==1.7 105 | 106 | ### Using the latest version of Pygal 107 | 108 | The latest version of Pygal is version 2.1.1. This is the version that will be installed if you don't specify a version for pip to install: 109 | 110 | $ pip install --user pygal 111 | 112 | or 113 | 114 | $ python -m pip install --user pygal 115 | 116 | If you use the latest version, you'll need to make some slight changes to the code in chapter 16 and chapter 17: 117 | 118 | - [Updates to Chapter 16 Pygal code](../../pcc/chapter_16/README.md#updates) 119 | - [Updates to Chapter 17 Pygal code](../../pcc/chapter_17/README.md#updates) 120 | 121 | [top](#) 122 | 123 | Updates 124 | --- 125 | 126 | Pygal has been updated to version 2; make sure you've read the notes about [installing Pygal](#installing-pygal) above. 127 | 128 | If you're using Pygal version 2.0 or higher you'll need to add one line to each file in order to render the charts correctly. Pygal has changed the way tooltips are displayed, so if you don't add this line you won't see any tooltips when you hover over the bars on a chart. 129 | 130 | Each time you make a chart in Pygal, add a line that tells Pygal to make an SVG file that renders correctly in a browser. For example: 131 | 132 | hist = pygal.Bar() 133 | hist.force_uri_protocol = 'http' 134 | 135 | This causes Pygal to configure the SVG rendering engine to work correctly for displaying the files in a browser. 136 | 137 | Page by page updates 138 | --- 139 | 140 | Code that appears in bold is new, or is modified from what appears in the book. 141 | 142 | ### p. 342, die_visual.py 143 | 144 | 
145 | hist = pygal.Bar()
146 | hist.force_uri_protocol = 'http'
147 |
148 | 149 | ### p. 343-344, dice_visual.py 150 | 151 | 
152 | hist = pygal.Bar()
153 | hist.force_uri_protocol = 'http'
154 |
155 | 156 | ### p. 345, different_dice.py 157 | 158 |
