Invalid Syntax while checking if skill list is empty

I am trying to extract skills from a resume which works fine but now I want to check if in case skill is empty then the program should open up a rawtext.json file but the problem is that as soon as I write elif to check if the skill is empty then, I get invalid syntax or unexpected indent.

def getSkills(sentences):
    try:
        sen=[]
        z=0
        for words in sentences:
            for i in range(len(words)):
                if(words[i][0].lower()=='skills') and words[i][1]=='NNP':
                    index =[z,i]
                    break
            z+=1

        skills=[]
        for i in sentences[index[0]][index[1]+1:]:
            if i[0].isalpha() and i[1]=='NNP':
                skills.append(i[0])
        return skills
            elif skills == []:
                with open('rawtext.json','r', encoding='utf-8') as f:
    data = json.load(f)
result = [x["name"].replace("@", " ").lower() for x in data]
print(result)
    else:
        return None
    except:
        return None

Can someone please guide me on how can I implement this logic? Thank you for your assistance in this regard.
