Conditional statement / If statement with Dataframes

I am trying to assign a value to column 'Percentage' based on multiple columns 'Class' and 'Value'

Below is a link that has my dataframe: https://filebin.net/fo2wk7crmwf0fycc

This is the logic that I want to be applied:

If df['Class'] equals 2 or 3, and if df['Value'] is less than 0.5, set df['Percentage'] to 0
If df['Class'] equals 2 or 3, and if df['Value'] is > 0.5 and <= 0.7, set df['Percentage'] to 0.25
If df['Class'] equals 2 or 3, and if df['Value'] is > 0.7 and <= 0.9, set df['Percentage'] to 0.5
Else set df['Percentage'] to 1

Below is an example of the output I am looking for:

Class	Value	Percentage
2	0.01	0
2	0.6	0.25
3	0.9	0.5
3	3	1

Thank you
