pandas - change df.index from float64 to unicode or string

Question

I want to change a dataframes\' index (rows) from float64 to string or unicode.

I thought this would work but apparently not:

#check type
type(df.in         


        

Answer 1

For python 3 and pandas 0.19 or latter versions, I found the following works fine for me

    # Python 3 (pandas 0.19 or latter versions)
    df.index.astype(str, copy = False)
