Change the default indexing of an array in pandas

I have a series object in python, created using pandas. The default indexing is 0,1,2,3...

I want the default indexing to be a,b,c,d,...

How do I do this?

Hey @Hannah, Hope you are doing good. Changing the indexing of an array is pretty simple. While initializing an array, you just have to add an additional parameter called index.

variable = pd.Series([1,2,3,4]index=['a','b','c','d'])

df = pd.DataFrame({'month': [1, 4, 7, 10],
                   'year': [2012, 2014, 2013, 2014],
                   'sale': [55, 40, 84, 31]})
print(df.set_index(['year', 'month']))

first print stmt gives default index,next print stmt gives default index change to month,third print stmt gives year month as index
