python: changing row index of pandas data frame [duplicate]

Question

I have a data frame called followers_df as below:

 followers_df               0 0         oasikhia  0     LEANEnergyUS 0  _johannesngwako 0     jamesbreenre 0   CaitlinFecteau 0  mantequillaFACE 0         apowersb 0       ecoprinter 0        tsdesigns 0      GreenBizDoc 0        JimHarris 0    Jmarti11Julia 0         JAslat63 0            prAna 0    GrantLundberg  0        Jitasa_Is 0     ChoosePAWind 0  cleanpowerperks 0          WoWEorg 0      Laura_Chuck 

I want to change this data frame into something like this:

 followers_df               0 0          oasikhia  1      LEANEnergyUS 2   _johannesngwako 3      jamesbreenre 4    CaitlinFecteau 5   mantequillaFACE 6          apowersb 7        ecoprinter 8         tsdesigns 9       GreenBizDoc 10        JimHarris 11    Jmarti11Julia 12         JAslat63 13            prAna 14    GrantLundberg  15        Jitasa_Is 16     ChoosePAWind 17  cleanpowerperks 18          WoWEorg 19      Laura_Chuck 

how can I do this? I tried:

     index = pandas.Index(range(20))      followers_df = pandas.DataFrame(followers_df, index=index) 

but it's giving me the following error:

  ValueError: Shape of passed values is (1, 39), indices imply (1, 20) 

thanks,

Answer 1

you can do

followers_df.index = range(20)
