```{python}
import pandas as pd
from src import data

df = data.from_yml()
```

Get interventions:

```{python}
df['intervention'].str.split(";").explode().str.strip().value_counts()
```

Get inequalities:

```{python}
df['inequality'].str.split(";").explode().str.strip().value_counts()
```

```{python}
df.groupby(["author", "year", "title"]).first().join(df['intervention'])
```

Unique values in chain method:

```{python}
(
    df.groupby(["author", "year", "title"])
    .agg(
        {
            "intervention": lambda _col:"; ".join(_col),
            "inequality": lambda _col:"; ".join(_col),
        }
    )
    .drop_duplicates()
    .explode("inequality")
    ["inequality"].str.strip()
    .value_counts()
)
```

Merge dataset so it is collected by *STUDY* not by *OBSERVATION*.
Any required columns can be calculated similar to the agg function here.

```{python}
by_study = (
    df.groupby(["author", "year", "title"])
    .agg(
        {
            "intervention": lambda _col: "; ".join(_col),
            "inequality": lambda _col: "; ".join(_col),
            "date": lambda _col: "; ".join(_col),
            "findings": lambda _col: "; ".join(_col),
            # "region": lambda _col: "; ".join(_col), # only accessible when merging with WB data
            # "income_group": lambda _col: "; ".join(_col),
        }
    )
    .reset_index()
    .drop_duplicates()
    .assign(
        # create de-duplicated joins for all observations
        intervention=lambda _df: _df["intervention"].apply(
            lambda _cell: set([x.strip() for x in _cell.split(";")])
        ),
        inequality=lambda _df: _df["inequality"].apply(
            lambda _cell: set([x.strip() for x in _cell.split(";")])
        ),
    )
)
```

```{python}
by_study = (
    df.groupby(["author", "year", "title"])
    .first()
    .reset_index()
    .drop_duplicates()
    .assign(
        # create de-duplicated joins for all observations
        intervention=lambda _df: _df["intervention"].apply(
            lambda _cell: set([x.strip() for x in _cell.split(";")])
        ),
        inequality=lambda _df: _df["inequality"].apply(
            lambda _cell: set([x.strip() for x in _cell.split(";")])
        ),
    )
)
```

```{python}
import re
by_intervention = (
    df.groupby(["author", "year", "title"])
    .agg(
        {
            "intervention": lambda _col: "; ".join(_col),
        }
    )
    .reset_index()
    .drop_duplicates()
    .assign(
        intervention=lambda _df: _df["intervention"].apply(
            lambda _cell: set([x.strip() for x in re.sub(r"\(.*\)", "", _cell).split(";")])
        ),
    )
    .explode("intervention")
)
sort_order = by_intervention["intervention"].value_counts().index

fig = plt.figure()
fig.set_size_inches(6, 3)
ax = sns.countplot(by_intervention, x="intervention", order=by_intervention["intervention"].value_counts().index)
plt.setp(ax.get_xticklabels(), rotation=45, ha="right",
         rotation_mode="anchor")
plt.show()
