add a row at top in pandas dataframe [duplicate]

Answer 1

This will work for me.

>>> import pandas as pd
>>> df = pd.DataFrame({'name': ['jon','sam','jane','bob'],
...            'age': [30,25,18,26],
...            'sex':['male','male','female','male']})     >>> df
   age  name     sex
0   30   jon    male
1   25   sam    male
2   18  jane  female
3   26   bob    male
>>> df.loc['a']=[45,'dean','male']
>>> df
   age  name     sex
0   30   jon    male
1   25   sam    male
2   18  jane  female
3   26   bob    male
a   45  dean    male
>>> newIndex=['a']+[ind for ind in df.index if ind!='a']
>>> df=df.reindex(index=newIndex)
>>> df
   age  name     sex
a   45  dean    male
0   30   jon    male
1   25   sam    male
2   18  jane  female
3   26   bob    male
