Indentationt error Python (if/else) : i have a problem with my code. I dont know why but the python compiler throw me an error about indentation in my "else"

    def enum2(q,k):
        n = q.length
        if k == n:
    	    #asdasdsa
	    else:
		    for i in range(0,n):
			    q[k] = i
			    if (isSafe(q,k)):
				    enum2(q,k+1)

        else:
       ^
    IndentationError: expected an indented block

i searched some spaces but i didnt find nothing just tabs.
