# **Print colored Numpy arrays / pandas DataFrames / Pandas Series / lists / dicts / tuples!** ```python pip install PrettyColorPrinter ``` #### **This is everything you have to do to use PrettyColorPrinter with pandas** ```python from PrettyColorPrinter import add_printer add_printer() #This function will add some methods to PandasObject #Let’s import pandas and create a DataFrame: import pandas as pd df=pd.read_csv(r"https://github.com/pandas-dev/pandas/raw/main/doc/data/air_quality_no2_long.csv") ``` ### Update 2022/12/27 You can switch between the colored version and the black/white version. ```python import pandas as pd from PrettyColorPrinter import add_printer, switch_color_bw add_printer(True) switch_color_bw() ``` ### Update 2022/10/08 Fixed a bug with empty DataFrames ### **Update 2022/10/05** ```python add_printer(overwrite_pandas_printer=False) If you pass overwrite_pandas_printer=True then the color printer will replace __str__ and __repr__ from pandas You can configure the color printer using: pd.color_printer_activate(print_stop:int=69,max_colwidth:int=300,repeat_cols:int=70) print_stop = maximum lines to print max_colwidth = maximum column width repeat_cols = for better readability, the columns are printed each x row This is how you switch back and forth between standard pandas and color printer: pd.color_printer_reset() #to standard pandas pd.color_printer_activate() #to color printer ``` ### Have a look ```python from PrettyColorPrinter import add_printer from a_pandas_ex_plode_tool import pd_add_explode_tools import pandas as pd pd_add_explode_tools() add_printer(overwrite_pandas_printer=True) data={'critic_reviews': [{'review_critic': 'XYZ', 'review_score': 90}, {'review_critic': 'ABC', 'review_score': 90}, {'review_critic': '123', 'review_score': 90}], 'genres': ['Sports', 'Golf'], 'score': 85, 'title': 'Golf Simulator', 'url': 'http://example.com/golf-simulator'} df = pd.Q_AnyNestedIterable_2df(data,unstack=False) #multiindex df2 = df.d_unstack() #normal index df #if you type df, you will get a colored dataframe instead of the regular pandas version ``` ![](https://github.com/hansalemaos/PrettyColorPrinter/raw/main/a12.png) ![](https://github.com/hansalemaos/PrettyColorPrinter/raw/main/a13.png) **All methods added to pandas start either with:** - **ds_** (for DataFrames and Series) - **s_** (only for Series) - **d_** (only for DataFrames) ### **All methods that are added to PandasObject** - **ds_color_print** - **ds_color_print_all** - **d_color_print_columns** - **d_color_print_index** - **ds_color_print_all_with_break** - **ds_color_print_context** ```python #If you want to see some examples: from PrettyColorPrinter import print_test_from_pandas_github print_test_from_pandas_github() #If you need help help(df.ds_color_print) qq_ds_print(max_rows: int = 1000, max_colwidth: int = 300, repeat_cols: int = 70, asnumpy: bool = False, returndf: bool = False) -> Union[pandas.core.frame.DataFrame, pandas.core.series.Series, NoneType] method of pandas.core.frame.DataFrame instance Parameters ---------- df : pd.DataFrame, pd.Series Array to print max_rows : int Stop printing after n lines (default is 1000) max_colwidth : int Width of each column (default is 300) repeat_cols : int (default is 70) Print columns again after n lines (default is 70) asnumpy: bool (default is False) Converts pandas DataFrame to np before printing. If there are duplicated columns in a Pandas DataFrame, it changes to printasnp = True (default is False) returndf: bool (default is False) return the input DataFrame to allow chaining ``` ### Using PrettyColorPrinter without pandas ** The function **pdp** can be used without pandas. Doing it this way, you are not restricted to PandasObjects. **You can print lists, dicts, tuples, np.arrays, pd.DataFrames and pd.Series** ** ```python from PrettyColorPrinter import pdp ```
