|
## 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}
|
|
```
