Program 16: To add the row at the end in the DataFrame

# Import pandas library
import pandas as pd

# Define a dictionary containing employee data
data = {'Name':['Adit', 'Ekam', 'Sakshi', 'Anu'],
'Age':[27, 24, 25, 30],
'Address':['Delhi', 'Kanpur', 'Meerut', 'Indore'],
'Qualification':['M.Sc.', 'MA', 'MCA', 'Ph.D.']}
# Convert the dictionary into DataFrame
df = pd.DataFrame(data)

# Add a new column 'Salary' to the DataFrame
df['Salary'] = [50000, 45000, 55000, 60000]

# Add a new row to the DataFrame using DataFrame.loc[]
new_row = {'Name': 'Himanshi', 'Age': 29, 'Address': 'Mumbai', 'Qualification':
'B.Tech', 'Salary': 52000}
df.loc[len(df)] = new_row

# Display the DataFrame with the new row
print("DataFrame with the new row:")
print(df)
Output:

DataFrame with the new row:
Name Age Address Qualification Salary
0 Adit 27 Delhi M.Sc. 50000
1 Ekam 24 Kanpur MA 45000
2 Sakshi 25 Meerut MCA 55000
3 Anu 30 Indore Ph.D. 60000
4 Himanshi 29 Mumbai B.Tech 52000
To add a new row in the middle of the DataFrame, you can use the DataFrame.iloc[] method to specify the index where
you want to insert the row.

Program 17: To add the row at middle in the DataFrame
# Import pandas library
import pandas as pd

# Define a dictionary containing employee data
data = {'Name':['Adit', 'Ekam', 'Sakshi', 'Anu'],
'Age':[27, 24, 25, 30],

'Address':['Delhi', 'Kanpur', 'Meerut', 'Indore'],
'Qualification':['M.Sc.', 'MA', 'MCA', 'Ph.D.']}
