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)
