I need to assign values to a slice of dataframe that can be best referenced with label or boolean on the index and position on the columns. For example (using .loc as placeholder for the desired slicing method): df.loc[df['a'] == 'x', -12:-1] = 3 obviously this doesn't work, with which I get: TypeError: cannot do slice indexing on <class 'pandas.core.indexes.base.Index'> with these

In my procedure I need to step through the rows of the table twice.
