Difference between __str__ and __repr__?
...
In my unit tests I always check that eval(repr(foo)) evaluates to an object equal to foo. You're right that it won't work outside of my test cases since I don't know how the module is imported, but this at least ensures that it works in...

Date ticks and rotation in matplotlib
...ail_plot calls, eg
plt.xticks(rotation=70)
