These lines of code are applying lambda functions to certain columns in the data dataframe.

The first line is applying the lambda function replace_pro to the 'Province' column. This lambda function likely replaces certain values in the 'Province' column with standardized values. The actual logic of the replace_pro function is not shown.

The second and third lines are applying the lambda function replace_dead to the 'Number of Injuries' and 'Number of Deaths' columns, respectively. This lambda function likely replaces certain values in these columns with standardized values. The actual logic of the replace_dead function is not shown
