Converting a dataframe into a config file

def load_config_report(config_file_path):    config = configparser.ConfigParser()    pharmacy_settings = pd.read_excel(config_file_path,                                      sheet_name='pharmacy_settings')    for each in pharmacy_settings['facility_name']:        config[each]['facility_alias'] = pharmacy_settings['facility_alias']        config[each]['facility_group_id'] = pharmacy_settings['facility_group_id']        config[each]['invoice_num'] = pharmacy_settings['invoice_num']    with open('X:\\Reports\\Invoices\\config.ini', 'w') as configfile:        config.write(configfile)

Trying to convert the contents of an excel file into a .ini file. First column is the [section], remaining columns are variables in that section. Currently getting a KeyError due to how I'm iterating/slicing the dataframe. Is this a good approach to achieve this?
