What is Lea?
-----------------
Lea is a Python module for playing with discrete probability distributions
in an intuitive way. This ranges from simple dice, coin flipping, random
sampling . to Bayesian networks, Probabilistic Programming (PP), machine
learning and symbolic computation. One salient feature of Lea is the ability
to change the probability representation, viz. float, fractions, decimals,
and symbols. Lea can be used for education, AI, PP, etc. Comprehensive
tutorials are available online (see Wiki pages). For a 5 minutes tour, check
out the poster presented at PROBPROG2020 conference:
https://probprog.cc/2020/assets/posters/fri/69.pdf .

What's new in Lea 4.0.0?
---------------------------------
Here are the major changes since Lea 3.4.6:
- optimization of conditional probabilities ('given' method), BN and
fractions' display,
- new "such_that" and "as_depending_on" methods to ease CPT creation (e.g.
the Monty Hall problem)
- persistent display options, including one line display of probability
distributions,
- fixes for mixing different probability representations,
- indicators as method to call with parenthesis (e.g. x.mean() instead of
x.mean),
- extension of P, Pf, given_prob, is_any_of and is_none_of methods,
- improved method documentation and code structure,
- support to Python 3.8+ only (for Python 2.7+, you may still use Lea 3 -->
https://pypi.org/project/lea/3.4.6/ )
