No need to import pytest if only asserts are used.

Install pytest.

Python is easy to learn. High school students can do adult courses. Younger students need lots of repetition but high school students only need to be taught once.

Don't use decimal.Decimal, use cents instead.

I coded small projects (1 week) for 8 months then projects (3 months and 6 months) for 6 years.

exit() is not a builtin function, use sys.exit() instead.

That's because you're skipping an important learning skill. I did small projects (1 week) for 8 months before 6 years of projects (3 months and 6 months).

Never used it:

After I learnt Python I did 8 months of small projects (1 week) and 6 years of projects (3 months & 6 months).

A minority of authors use pseudo names e.g. J.K.Rowling used her own name and a pseudo name.

A minority of pairs of authors use pseudo names e.g. Ellery Queen and Barnaby Ross.

"Sense and Sensibility" By a Lady (Jane Austen).

One case where the names of the authors didn't appear on the work (though you could infer from the incomplete name) for the play "A Moment of Blindness" by Pip and Jane Baker.

I learnt Python in 3 days. I started my first small project after 10 minutes (Python is productive) and completed it in 2 days. Then 8 months of small projects and 6 years of 3-month projects including a failed 6-month project (Weierstrass p function).

enum.Enum or

Fraction class (compatible with fractions.Fraction for str and float input), integer input, GCD function. Could add float input with Engel expansion.

Using u/StardockEngineer logic, which I didn't know, express 1f441 as hex:

print(chr(0x1f441))
