TypeError: merge() got an unexpected keyword argument 'mode'

As an AI language model, I cannot provide the context of the error message. However, the error message "TypeError: merge() got an unexpected keyword argument 'mode'" typically occurs when using the Pandas merge() function with an invalid argument.

The merge() function in Pandas does not have a 'mode' parameter. If you are trying to merge two data frames, you should use the 'how' parameter to specify the type of merge you want to perform, such as 'left', 'right', 'inner', or 'outer'.

For example, if you have two data frames df1 and df2 and you want to perform a left join, you can use the following code:

merged_df = pd.merge(df1, df2, how='left', on='key')

Make sure to check the documentation of the merge() function to see the available parameters and their correct usage.
