Creating a dataframe from a dict where keys are tuples in python

Creating a dataframe from a dict where keys are tuples in python

To create a pandas DataFrame from a dictionary where keys are tuples, you can preprocess the dictionary keys to convert them into suitable labels for the DataFrame columns. Here's how you can do it:

import pandas as pd # Sample dictionary with tuple keys data_dict = { (1, 'A'): 100, (2, 'B'): 200, (3, 'C'): 300 } # Preprocess tuple keys to separate columns and values preprocessed_data = [{'Tuple1': key[0], 'Tuple2': key[1], 'Value': value} for key, value in data_dict.items()] # Create a DataFrame from the preprocessed data df = pd.DataFrame(preprocessed_data) print(df)

In this example, we create a DataFrame named df using the preprocessed data. The preprocessed_data list comprehension converts each tuple key into separate columns ('Tuple1' and 'Tuple2') and also includes the corresponding values. Adjust the column names according to your preference.

The resulting DataFrame will look like this:

 Tuple1 Tuple2 Value 0 1 A 100 1 2 B 200 2 3 C 300

This approach effectively converts the dictionary with tuple keys into a pandas DataFrame while preserving the tuple elements as separate columns.
