'DataFrame' object has no attribute 'ix'

In recent versions of pandas, the `.ix` indexer has been deprecated and removed.

Instead, you can use `.loc` or `.iloc` indexer to access the elements of a DataFrame.

`.loc` is a label-based indexer, which means you can access the elements based on their index label. For example:

df.loc[0, 'column_name']

`.iloc` is an integer-based indexer, which means you can access the elements based on their integer position. For example:

df.iloc[0, 1]

If you are trying to access a specific row or column in a DataFrame, you can use `.loc` or `.iloc` with a colon to select all rows or columns. For example:

df.loc[:, 'column_name']
df.iloc[:, 1]
