How to remove list item if json exception in for loop

Need to remove list items that do not produce a json from for loop

list1 = [items]
list2 = []
for item in list:
    df = pd.DataFrame()
    try:
        df = pd.read_json('https://blahblahblah/'+item+'/blah')
        if Exception:
            list1.remove(item) ###I want to remove broken items so list1 and list2 are same length
    except Exception: pass
    newitem = (jsonthing/jsonthing)
    list2.append(newitem)
