JSON serialization of MongoDB ObjectID (ex-scope query)

I am confused howcome the variable temp_dict is available outside else condition? when I am saving the array to MongoDB which is setting the ObjectId on each item in the array. Json parser doesn't doesn't know how to serialize ObjectId. 

def read_temporary_file(filename, has_header=False):
    wb = load_workbook(filename=filename, use_iterators=True)
    ws = wb.get_active_sheet()  # ws is now an IterableWorksheet

    headers = []
    rows = []
    documents = []

    for row in ws.iter_rows():  # it brings a new method: iter_rows()
        if has_header:
            has_header = False
            for cell in row:
                headers.append(cell.internal_value)
        else:
            temp_dict = OrderedDict()
            for cell in row:
                temp_dict[cell.column] = cell.internal_value
            rows.append(temp_dict)
            documents.append(temp_dict)

    print("Saving documents to MongoDB")
    __save(documents)
    print("Printing %s" % temp_dict)
    return (headers, rows)

In Python, the entire function is the scope. Clauses like your else are not new scopes.
