How to convert a DataFrame into a dictionary in Pandas?
To convert a Pandas DataFrame into a dictionary, we can use the to_dict() method. Let's take an example and see how it's done.
Steps
- Create two-dimensional, size-mutable, potentially heterogeneous tabular data, df.
- Print the input DataFrame, df.
- Convert the DataFrame into a dictionary using to_dict() method and print it.
Example
import pandas as pd df = pd.DataFrame( { "x": [5, 2, 7, 0], "y": [4, 7, 5, 1], "z": [9, 3, 5, 1] } ) print "Input DataFrame is:\n", df print "Convert DataFrame into dictionary: \n", df.to_dict()
Output
Input DataFrame is: x y z 0 5 4 9 1 2 7 3 2 7 5 5 3 0 1 1 Convert DataFrame into dictionary: {'x': {0: 5, 1: 2, 2: 7, 3: 0}, 'y': {0: 4, 1: 7, 2: 5, 3: 1}, 'z': {0: 9, 1: 3, 2: 5, 3: 1}}
