import logging
logging.basicConfig(level=logging.INFO)

# encoding=utf8
import logging
logging.basicConfig(level=logging.INFO)
# other import
import ...
# your code
if __name__ == '__main__':
  pass

def basicConfig(**kwargs):
  _acquireLock()
  try:
    if len(root.handlers) == 0:
      filename = kwargs.get("filename")
      if filename:
        mode = kwargs.get("filemode", 'a')
        hdlr = FileHandler(filename, mode)
      else:
        stream = kwargs.get("stream")
        hdlr = StreamHandler(stream)
      fs = kwargs.get("format", BASIC_FORMAT)
      dfs = kwargs.get("datefmt", None)
      fmt = Formatter(fs, dfs)
      hdlr.setFormatter(fmt)
      root.addHandler(hdlr)
      level = kwargs.get("level")
      if level is not None:
        root.setLevel(level)
  finally:
    _releaseLock()
