convert a sqlite3 query result table into a pandas dataframe

The sqlite3 query returns a list of tuples. Here's a good way to convert the list of tuples into a pandas data frame.

def q():
    sql_c = " some query commands here"
    df = pd.DataFrame(dbc.execute(sql_c).fetchall())
   
    # get all column names
    cns = [d[0] for d in dbc.description]
    df.columns = cns

    return df
