If you want to add the column at specific position in the DataFrame, then you need to use the insert() function that
allows you to specify the index value where you want to insert the column.

Program 15: To add the column at specific position 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)

# Specifying values to new column
Salary = [50000, 45000, 55000, 60000]

# Index position where you want to insert the new column (zero-based)

index_position = 2 # Inserting the new column after the 'Age' column

# Insert new column at specified index position
df.insert(index_position, 'Salary', Salary)

# Displaying DataFrame
print(df)
Output:

Name Age Salary Address Qualification
0 Adit 27 50000 Delhi M.Sc.
1 Ekam 24 45000 Kanpur MA
2 Sakshi 25 55000 Meerut MCA
3 Anu 30 60000 Indore Ph.D.

Adding a New Row to the DataFrame
A new row can be added to a DataFrame by utilising the DataFrame.loc[] method. This method allows you to add rows
by specifying the index and the values.
