Add a row at top in pandas DataFrame

  • Last Updated : 29 Jul, 2021

Pandas DataFrame is two-dimensional size-mutable, potentially heterogeneous tabular data structure with labeled axes (rows and columns). 
Let’s see how can we can add a row at top in pandas DataFrame.
Observe this dataset first.
 

Python3




# importing pandas module
import pandas as pd
   
# making data frame
 
df.head(10)

Code #1: Adding row at the top of given dataframe by concatenating the old dataframe with new one. 
 

Python3




new_row = pd.DataFrame({'Name':'Geeks', 'Team':'Boston', 'Number':3,
                        'Position':'PG', 'Age':33, 'Height':'6-2',
                        'Weight':189, 'College':'MIT', 'Salary':99999},
                                                            index =[0])
# simply concatenate both dataframes
df = pd.concat([new_row, df]).reset_index(drop = True)
df.head(5)

Output: 
 

  
Code #2: Adding row at the top of given dataframe by concatenating the old dataframe with new one. 
 

Python3




new_row = pd.DataFrame({'Name':'Geeks', 'Team':'Boston', 'Number':3,
                        'Position':'PG', 'Age':33, 'Height':'6-2',
                        'Weight':189, 'College':'MIT', 'Salary':99999}, index =[0])
 
# Concatenate new_row with df
df = pd.concat([new_row, df[:]]).reset_index(drop = True)
df.head(5)

Output: 
 

  
Code #3: Adding row at the top of given dataframe by concatenating the old dataframe with new one using df.ix[] method.
 

Python3




new_row = pd.DataFrame({'Name':'Geeks', 'Team':'Boston', 'Number':3,
                        'Position':'PG', 'Age':33, 'Height':'6-2',
                        'Weight':189, 'College':'MIT', 'Salary':99999}, index =[0])
 
df = pd.concat([new_row, df.ix[:]]).reset_index(drop = True)
df.head(5)

Output:
