'return file inside an if statement

I am trying to return only the response of status code that is 200, and its inside an if statement, when I put the return preddata inside the if statement, nothing gets returned, when I put it outside, I get an error that UnboundLocalError: local variable 'preddata' referenced before assignment, how can I solve this, this is the code:

def obtain_data(url):
    response = requests.get(url)
    if response.status_code == 200:
        # getting data in the json format
        preddata = response.json()
        preddata=(pd.DataFrame(preddata['hourly']))     
        return preddata

If you got None returned, it probably means that response.status_code == 200 is False.

(Other option would be that DataFrame constructor generates None, but not possible in the context.)
