pyuoyweek is a (much nicer) Python reimplementation of one of my previous projects, uoyweek. It gives the current date string as formatted by the University of York. For example, spr/2/thu would refer to Thursday on the 2nd week of Spring term.

pyuoyweek uses Python 3 -- it is not compatible with Python 2.
If you just want to use pyuoyweek, you can simply download uoyweek.py - it's all self-contained. If you'd like, you can copy uoyweek.py to a folder on your $PATH and rename it to uoyweek, basically turning it into a command that you'd call with uoyweek.
You can also clone the repository if you'd like to add new term dates (there's a helpful script in tools/ for that) or otherwise contribute :)

Although pyuoyweek is not on pypi, you can install the latest version via pip with the following command:

pip install git+https://github.com/lukemoll/pyuoyweek.git

Simply run ./uoyweek.py or python3 uoyweek.py. More options can be found with the -h flag, such as lowercase (-l) or short output (-s).

You may want to use this in your own python projects instead of just calling the script - while the source is fairly straightforward, here are some points you may be interested in:

# uoyweek.py should be in the directory as the script you're importing it from
import uoyweek, date

period = uoyweek.getPeriod(date.today()) 

print(period.name) # term or holiday name
print(period.date) # start date of term or holiday

if type(period) is Term:
    print("Week " + period.getWeekNum(date.today()))
    # If you're specifying something other than date.today(),
    # it needs to be the same date you provided to getPeriod()

print(period.toString(date.today()))
# as with getWeekNum(), this needs to be the same date you 
# provided to getPeriod()

The dates list is also importable, and is in chronological order. If you select a Period from the list, you can assume that it ends at the start of the next Period in the list.

Although the python script with a shebang is arguably more portable than an executable, you can create one if you'd like:
With cython and gcc:

$ cython3 uoyweek.py --embed
$ ls *.c
uoyweek.c
$ gcc uoyweek.c -I<include directory for Python> -L<library containing libpython> -l<libpython* without the lib> -o uoyweek
