# Mapytex Formal calculus with explanation python module and exercises creation tools. [French wiki](https://opytex.org/pymath) ## Installing Install and update with [pip](pypi.org) ``` pip install -U mapytex ``` ## Examples ### Simplify expressions and explain steps ``` python >>> from mapytex import Expression >>> ajout_fractions = Expression("2 / 5 + 2 / 3") >>> resultat = ajout_fractions.simplify() >>> print(resultat) 16 / 15 >>> for s in resultat.explain(): ... print(s) ... 2 / 5 + 2 / 3 2 * 3 / 5 * 3 + 2 * 5 / 3 * 5 6 / 15 + 10 / 15 ( 6 + 10 ) / 15 16 / 15 ``` ### Random expression generator ``` python >>> from mapytex import Expression >>> ajout_fraction = Expression.random("{a} + {b} / {c}") >>> print(ajout_fraction) 2 + 3 / 5 ``` ### Render in latex ``` python >>> from mapytex import Expression >>> Expression.set_render("tex") >>> ajout_fractions = Expression("2 / 5 + 2 / 3") >>> for i in ajout_fractions.simpliy().explain(): ... print(i) ... \frac{ 2 }{ 5 } + \frac{ 2 }{ 3 } \frac{ 2 \times 3 }{ 5 \times 3 } + \frac{ 2 \times 5 }{ 3 \times 5 } \frac{ 6 }{ 15 } + \frac{ 10 }{ 15 } \frac{ 6 + 10 }{ 15 } \frac{ 16 }{ 15 } ``` ### Statistical tools ``` python >>> from mapytex import Dataset >>> d = Dataset.random(10, "Poids des sacs (kg)", "gauss", (4, 1), v_min=1) >>> print(d) [3.03, 5.94, 4.46, 2.58, 5.32, 3.22, 5.75, 4.22, 1.81, 4.71] >>> d.mean() 4.1 >>> d.effectif_total() 10 >>> d.sum() 41.04 >>> print(d.tabular_latex(2)) \begin{tabular}{|c|*{5}{c|}} \hline 3.03 & 5.94 & 4.46 & 2.58 & 5.32 \\ \hline 3.22 & 5.75 & 4.22 & 1.81 & 4.71 \\ \hline \end{tabular} >>> w = WeightedDataset([1, 2, 3, 4], "Enfants", [10, 11, 12, 13]) >>> print(w) {1: 10, 2: 11, 3: 12, 4: 13} >>> print(w.tabular_latex()) \begin{tabular}{|c|*{4}{c|}} \hline Enfants & 1 & 2 & 3 & 4 \\ \hline Effectifs & 10 & 11 & 12 & 13 \\ \hline \end{tabular} ```
