how to save powerpoint presentation as read only recommended

Question

I am using the Iris flower data set:

In the species, I have three different items of information:

 print(df['Species'].unique())
['setosa' 'versicolor' 'virginica']

I want to filter out all rows and all rows where Species= 'setosa' and Petal.width'= 0.4:

df[df['Species']!='setosa' & (df['Petal.width'] != '0.4')]

The problem is that this function delete all rows which contain df['Species']=='setosa' and all rows which contains df['Petal.width'] == '0.4'.

I want to apply two conditions in the same time.

How do I solve the problem?

Solution

Goto File -> Info-> Protect Presentation and select the option that best suits your needs. Based on your description, you need to select 'Mark as Final'. Here's a screenshot that shows the location of the various tabs.
