karma = karma * 0.25

which can be written as:

karma *= 0.25

If this is inside a function (as it should be!) you will need to indent the line, and include a declaration at the top of the function:

     global karma
     karma *= 0.25


However, are you sure you want to multiply their karma by 25%? That makes it smaller. Perhaps you want to INCREASE it by 25%, which would be calculated like this:

     global karma
     karma *= 1.25


or perhaps:

     karma = karma + 0.25*karma
