n DataFrame, by default new column added as the _____________ columnFirst (Left Side)SecondLast (Right Side)Any where in dataframe

In a DataFrame, by default, a new column is added as the Last (Right Side) column. This is a standard behavior in pandas, a popular data manipulation library used in Python, where any new column will be appended to the end of the existing columns.

Explanation

When you create a DataFrame and decide to add a new column, using either the assignment operator or the insert() method, it will appear at the end of the DataFrame unless specified otherwise. For example, if you use df['new_column'] = values, this new column will be automatically added to the last position.

If you need to place the column in a specific location, you can use the insert() function that allows you to specify the index at which the new column should be added. However, without any additional parameters, new columns will consistently end up at the far right of the DataFrame structure, making data management and organization seamless for users.
