Spread the love

You have a pandas dataframe and you want to convert it to a python dictionary.

Solution –

To convert a pandas dataframe into a python dictionary, we use the pd.DataFrame.to_dict() method.

# import pandas
import pandas as pd

# read the csv file in pandas
df = pd.read_csv('../data/Restaurant.csv')

# convert df to dict

The df.to_dict() method also has a orient parameter that let’s you decide how you want to do the orientation of the dictionary. By Default it is – ‘dict’ (default) : dict like {column -> {index -> value}}

If you want you can change this orientation to a list like this – ‘list’ : dict like {column -> [values]}


You can find other options for the orientation here – pandas to_dict

  1. Create Pandas DataFrame from Lists and List of Lists.

  3. Create a Pandas Series from a list.
