[Python] Replace column values if it repeats the same character

I have a dataframe like

df = pd.DataFrame({'team': ['Red', 'Blue', 'Yellow', 'Green'],
'points': [11, 7, 8, 10],
'other': ["kk;aaa;;;", ";;bb;;", ";", ";;;;"]})


I would like to replace all cells that contain only ";" with "" (empty cells). There may be only 1 or many ";" in a row. If there is anything in the cells other than ";", I would like to leave them as is.

In my dataframe the other column would become:

other
kk;aaa;;;
;;bb;;
#(nothing)
#(nothing)
