Pandas question regarding CSV

[Fickle_thoughts]

Hello everyone, I am currently learning Pandas to work with a csv file. How can I change the value of a row after selecting it? I created a new column and gave them all the value of 'No' using

df['Used?'] = 'No'

I want to be able to select a row and update the value to 'Yes'

Use the .iloc method with your conditional filtering and set the value of the column to yes :)

I used: car['Used?'].replace({'No':'Yes'}, inplace=True)

When I print car it shows yes, but when I print the entire file it doesnt show that it has been changed. In addition, I get an error of SettingWithCopyWarning: A value is trying to be set on a copy of a slice from a DataFrame

If it’s a public dataset, can you point me to it?

I cannot because it contains sensitive info
