a code with for loops and if statements that displays the wrong message

strong text when i run this code it still shows up with the "search unsuccessful" message, could anyone help me figure out why? my code. I know that it has a loop in it but i cannot figure out how to make the code stop looping once it has found all of the positions of the word in the sentence.

    sentence= "the hat ran away from the cat"
    print(sentence)
    word_to_find= input("write word from sentence")
    senLow= sentence.lower()
    word= word_to_find.lower() 
    senList= senLow.split()

    for pos in range(len(senList)):
        if word== senList[pos]:
            print(word, "found in position:", pos+1)

    else :
       print ("search unsuccessful")
