ConfigParser problem Python -


i'm having problem append config file. here's want create;

[section1] val1 = val2 val3 = val4

but when run following code see configparser.nosectionerror: no section: 'section1'

import configparser  cfg = configparser.rawconfigparser() cfg.set("section1", "val1", "val2")  f = open("example.cfg", "a") cfg.write(f)

if add

if not cfg.has_section("section1"):     cfg.add_section("section1")

and then, get;

[section1] val1 = val2  [section1] val3 = val4

could point me i'm doing wrong? thanks

i fleshed out code put bit. reading existing file before checking section? also, should writing whole file @ once. don't append.

import configparser  cfg = configparser.configparser() cfg.read('example.cfg')  if not cfg.has_section('section1'):     cfg.add_section('section1')  cfg.set('section1', 'val1', 'val2') cfg.set('section1', 'val2', 'val3')  f = open('example.cfg', 'w') cfg.write(f) f.close()
