I want to use an IF/ELSE-Statement to define a field in the attribute table of my raster. Therefore I have a field "VALUE". The condition should be: If "VALUE" < 4 ...then use die field "A".....if "VALUE" > 4 then set 0.5.

I was searching for answers but couldn't find a proper one.

In Python:

def function(field):
    if field>4:
         return "0.5"
    else:
         return "A"

And below:

function(!choose from Fields!)
