Pandas loc to get rows based on column labels using callback functions from DataFrame

We can get rows and data based on column labels of a DataFrame by using loc(). Difference between iloc and loc loc is label based so we have to use column names. iloc is position based ( integer ).
WE can get first row , last row, any row based on various column labels . Similarly we can get the rows using a range of column values of the DataFrame. WE can get value at any position also.
We can use callable function with loc to use any logic to get the records.
