'DataFrame' object has no attribute 'strip'

The error message "'DataFrame' object has no attribute 'strip'" typically occurs when you try to apply the `strip` method to a DataFrame object in Python.

The `strip` method is a string method used to remove leading and trailing whitespace from a string. However, it cannot be directly applied to a DataFrame object because it operates on individual strings, not entire data frames.

To fix this error, you need to identify the specific column or value within the DataFrame that you want to strip, and then apply the `strip` method to that specific element. For example, if you have a DataFrame column named "column_name" and you want to strip leading and trailing whitespace from its values, you can use the `str.strip` method in combination with the `apply` function:

df['column_name'] = df['column_name'].apply(lambda x: x.strip() if isinstance(x, str) else x)

This code checks if the value is a string before applying the `strip` method to avoid errors caused by non-string values.
