import pandas as pd # Sample DataFrame data = {'ID': [1, 2, 3], 'Name': ['Alice', 'Bob', 'Charlie']} df = pd.DataFrame(data) # New row data new_row = {'ID': 4, 'Name': 'David'} # Append the new row df = df.append(new_row, ignore_index=True) # Display the ...
Now, let’s prepare the new row and add it to the top of the DataFrame. # Create a new DataFrame for the row to be added new_row = pd.DataFrame({'ID': [0], 'Plan': ['Free'], 'Cost': [0]}) # Use concat() to add the new row at the top df = pd.concat([new_row, ...
The resultingfinal_dfDataFrame includes a total row for each ‘Region’, under the ‘Plan_Type’ labeled as ‘Total’.
# Example 5: Using pandas.concat() # To add a row new_row = pd.DataFrame({'Courses':'Hyperion', 'Fee':24000, 'Duration':'55days', 'Discount':1800}, index=[0]) df2 = pd.concat([new_row,df.loc[:]]).reset_index(drop=True) ...
new_row=pandas.DataFrame({'students':['Emily'],'marks':[30],'id_no':[8]}) data1=pandas.concat([data1,new_row],ignore_index=True) print('\nAfter Adding Row to DataFrame:\n',data1) In the above code lines: The “pandas” library is imported, and “DataFrame” with three columns...
In the above code, we used the len(df) method of the pandas to fetch the index of the last row in the DataFrame and added one to get the index of the new row. We after that used the loc[] method to add the new row to the end of the existing DataFrame.Add multiple rows to ...
1. Add rows to dataframe Pandas in loop using loc method We can use the loc indexer to add a new row. This is straightforward but not the most efficient for large DataFrames. Here is the code to add rows to a dataframe Pandas in loop in Python using the loc method: import pandas as...

In Pandas, you can add a new column to an existing DataFrame using the DataFrame.insert() function, which updates the DataFrame in place. Alternatively, you can use DataFrame.assign() to insert a new column, but this method returns a new DataFrame with the added column....
