Assigning Multiple Column Values In A Single Row Of Pandas Dataframe, In One Line

I'm trying to Assign multiple values to a single row in a DataFrame and I need the correct syntax. See the code below. import pandas as pd df = pd.DataFrame({ 'A': range(10), 'B

Solution 1:

Use loc (and avoid chaining):

In [11]: df.loc[3] = ['V1', 4.3, 2.2, 2.2, 20.2]

This ensures the assigning is done inplace on the DataFrame, rather than on a copy (and garbage collected).

You can specify only certain columns:

 In [12]: df.loc[3, list('ABCDE')] = ['V1', 4.3, 2.2, 2.2, 20.2]
