[965] Generate a new empty DataFrame with the same columns as an existing DataFrame in Pandas
To generate a new empty DataFrame with the same columns as an existing DataFrame in Pandas, you can use the pd.DataFrame
constructor and pass the columns from the existing DataFrame. Here's an example:
import pandas as pd # Sample DataFrame existing_df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]}) # Create a new empty DataFrame with the same columns new_empty_df = pd.DataFrame(columns=existing_df.columns) print(new_empty_df)
In this example, pd.DataFrame(columns=existing_df.columns)
creates a new empty DataFrame (new_empty_df
) with the same columns as the existing_df
.
Adjust the columns and other parameters based on your specific use case.
