Pandas does not usually mutate inplace unless an inplace kwarg is offered.

I think you just need to reassign your dataframe to the pivoted version.

Additionally you should try to use chaining and vertical alignment when possible and practical.

Also to add a code block just use 3 tildas to start and end you code block.

pivot_table_df = (view_data_df
                  .pivot_table(values = 'Measure Values', 
                               index=['C Week','NT Login','Site'],
                               columns = 'Measure Names', 
                               aggfunc=sum)
                  .reset_index()
                  )
print(pivot_table_df)

This very clearly shows that we are starting with view_data_df, making a pivot table, resetting the index, and storing all of those changes in pivot_table_df. Hopefully, this is what you need.
