# pandas-parallel-apply
`df.apply(fn)`, `df[col].apply(fn)` and `series.apply(fn)` wrappers with tqdm included
## Installation
`pip install pandas-parallel-apply`
## Examples
See `examples/` for usage on some dummy dataframe and series.
## Usage
## 1. Procedural
### Apply on each row of a dataframe
`df.apply(fn)` -> `apply_on_df_parallel(df: pd.DataFrame, fn: Callable, n_cores: int, pbar: bool = True)`
### Apply on a column of a dataframe and return the Series
`df[col].apply(fn, axis=1)` -> `apply_on_df_col_parallel(df: pd.DataFrame, col_name: str, fn: Callable, n_cores: int, pbar: bool = True)`
### Apply on a series and return the modified Series
`series.apply(fn)` -> `apply_on_seris_parallel(series: pd.Series, fn: Callable, n_cores: int, pbar: bool = True)
### Switches for boolean parallel/non-parallel
`apply_on_df/df_col/series_maybe_parallel(*, parallel: bool, n_cores: int, pbar: bool = True)`
## 2. Object Oriented Programming
### Apply on each row of a dataframe
`df.apply(fn)` -> `DataFrameParallel(df, n_cores: int, pbar: bool = True).apply(fn)`
### Apply on a column of a dataframe and return the Series
`df[col].apply(fn, axis=1)` -> `DataFrameParallel(df, n_cores: int, pbar: bool=True)[col].apply(fn, axis=1)`
### Apply on a series
`series.apply(fn)` -> `SeriesParallel(series, n_cores: int, pbar: bool=True).apply(fn)`
That's all.
