Intro — What We’re Doing
Here’s the list:
- install Python/Tkinter,
- check the install to make sure everything’s working, and
- (if you’re using Linux or one of the BSD’s) install fonts (potentially) common to all OS’s.
It’s best to install the 64-bit version of Python. But, if for any reason you can’t, the 32-bit version will also do.
For those operating systems that use them (Windows and MacOS mostly), installers can be downloaded from here.
One more thing… depending on how much time has passed since the writing of this post, version numbers may have changed. In that case, just make the appropriate substitution. The procedures, however, will likely still be the same. If they do change, I’ll make sure this page is updated.
Now, on to specifics.
- start the installer,
- when the dialog appears, make sure to check the box at the bottom to:
- Add Python 3.x to PATH,
- from there, just follow the prompts.
Something to note… The default installation on Windows sets up an alias so you can run Python by simply typing:
su to or log in as
root. Alternatively, you can precede each of the commands below with
Locate the latest Python version:
pkg search python
pkg install python-xxx
Locate the latest version of tkinter:
pkg search tkinter
pkg install py39-tkinter-3.9.1_6
Chances are, you’re using a Debian/Ubuntu-based Linux release. If so, you’re likely familiar with
apt. If you’re using SUSE Linux or another distro that doesn’t use
apt, you may have to build Python from source and that’s beyond the scope of this blog. However, in a case like that, you likely don’t need any explanation on how to install Python, anyway. If you do, though, I refer you to this page on Real Python and we’ll talk again in a few hours once you’re finished.
Getting back to the subject at hand…
Install using the
apt package manager…
- hook up the repository:
sudo add-apt-repository ppa:deadsnakes/ppa
- make sure everything’s up to date:
sudo apt-get update
- find the latest Python (without venturing out onto the bleeding edge):
sudo apt-cache search python
- install it (and, of course, substitute the actual minor version for the
sudo apt-get install python3.x python3-pip
Just download and install. That’s it.
Well, one other thing you’ll likely want to do is add Python to the system path. This means you can simply type
python <script>.py to launch a script instead of typing the entire installation path name. Here’s a step-by-step procedure:
- open a Terminal,
- start a text editor:
sudo nano /etc/paths
- type your password when asked,
- (the contents of the
PATHvariable will appear as a list), so
- at the end of this list, type the full path of the Python install directory,
Ctrl + Xto quit, and
Yto save the changes.
Configure an Alias
(Optional, but Recommended)
You can run Python by typing
py no matter which OS you’re using. In Windows, it’s set up during the install, but to set this alias in other OSes, read on.
Linux or BSD
Create or edit
.bashrc in your home directory and add this line:
And, again, if you’re using a later version of Python, substitute the proper version number.
Note: Restart the shell for this to take effect.
To set up an alias:
- launch Terminal
- go to your home directory:
- create or edit the shell profile:
- add the alias:
- refresh the shell so the alias takes effect:
No matter which OS you’re using, if you followed the above recommendations, you can now check that Python is working by opening a shell/terminal/Terminal/Command Prompt and typing:
And to make sure tkinter is working properly:
py -m tkinter
This should open a small tkinter window that shows which version of tkinter you have. It should be 8.6 or later to follow the demos on this blog.
If you’re using a UNIX-like OS, there’s a slim chance that tkinter isn’t installed at this point or isn’t up to date. If that’s the case, type:
pip install tk
Then rerun the
py -m tkinter command to make sure you’re up-to-date.
Just one more thing (if you’re using Linux or a BSD) and then we’re ready to roll…
Install Core Fonts for the Web
(Optional, but Highly Recommended)
Let’s establish a baseline for fonts so we’re all on the same page.
We don’t need more than a few different fonts for the types of demos that’ll be covered here, but in the interests of flexibility and (reasonably) good design, we’ll want at least the following:
- a couple of serif fonts,
- a couple sans-serif,
- a fixed-width (monospace) font or two, and
- something playful for when we want a sense of whimsy.
Core Fonts for the Web gives us:
- Andalé Mono (fixed width),
- Arial (sans-serif),
- Arial Black (sans-serif),
- Comic Sans MS (fanciful),
- Courier New (fixed width,
- Georgia (serif),
- Impact (sans-serif),
- Times New Roman (serif),
- Trebuchet MS (sans-serif),
- Verdana (sans-serif), and
- Webdings (weird stuff).
These give us a couple of choices for each of the font styles listed above. And thanks go to Microsoft for making these fonts available to everyone on all operating systems.
If you’re working on Windows or MacOS, these fonts (with the exception of Andalé Mono) are installed along with the OS, but they’re also free to use with Linux and the BSD’s.
MS Webfonts on GhostBSD/FreeBSD
Log in or
root to install and configure them. (Or, as before, use
sudo before each of the following commands.)
pkg search webfonts pkg install webfonts-<VERSION> touch /usr/local/etc/X11/fontpath.d/fontpath.conf
To configure, just edit
/usr/local/etc/X11/fontpath.d/fontpath.conf and add these lines:
Section "Files" ModulePath "/usr/local/lib/xorg/modules" FontPath "/usr/local/share/fonts/webfonts" EndSection
MS Webfonts on Linux (Apt)
Make sure you’re using an appropriate repository:
sudo add-apt-repository multiverse
install the fonts:
sudo apt update sudo apt install ttf-mscorefonts-installer
The installer will ask you to agree to the license and—since you won’t be signing away your firstborn—you might as well.
Once that’s done, update your font cache:
sudo fc-cache -f -v
And now that that’s all sorted out, it’s way past my bedtime, so I’ll sign off. Next time we’ll start by looking into some windows… through some windows…? Out some windows…?
Whatever. I’ll see you then.

And have a great day!
