1. Pandas get index values in Python using df.index property We can use thedf.indexproperty to get the index from the Pandas dataframe. By default, thedf.index property in Python Pandasreturns the type of Index in a range. Let’s see an example to get index values in Pandas dataframes...
In case the answer for Q1 and Q2 was unique index values, now the same, but with repetitions, as number of data rows in index range. I know the answers to the above questions in the case of columns which are not indexes, but in the indexes case, after a long research in the web ...
