    x=int(input("select the option:"))
    if x==1:
        y=input("Input name:")
        z=input("Input Phone:")
        note[y]=z
    elif x==2:
        y=input("Input name:")
        print ("no HP:", note[y])
    elif x==3:
        for key, value in note.items():
            print ("nama/HP ->", key, ":", value)
