I have the next situation. I try to overwrite method send_error in BaseHTTPRequestHandler in BaseHTTPServer.py file. BaseHTTPServer.py has such structure concerning send_error method:
def _quote_html(html):
blah
blah
class HTTPServer():
blah
blah
class BaseHTTPRequestHandler():
blah
blah
def send_error(self):
blah
blah
content = (self.error_message_format %
{'code': code, 'message': _quote_html(message), 'explain': explain})
Here inside send_error method _quote_html function is called. It works inside BaseHTTPServer.py file but if create my own httphandler, inherit from BaseHTTPRequestHandler and try to overwrite send_error, my function send_error can not access _quote_html function located in BaseHTTPServer.py file outside of BaseHTTPRequestHandler class:
Traceback (most recent call last):
File "/usr/lib/python2.7/SocketServer.py", line 593, in process_request_thread
self.finish_request(request, client_address)
File "/usr/lib/python2.7/SocketServer.py", line 334, in finish_request

self.handle_one_request()
File "/python_codes/Junior/Level1/C&C/HttpServer/HttpHandler.py", line 26, in handle_one_request
if not self.parse_request():
File "/usr/lib/python2.7/BaseHTTPServer.py", line 286, in parse_request
self.send_error(400, "Bad request syntax (%r)" % requestline)
File "/python_codes/Junior/Level1/C&C/HttpServer/HttpHandler.py", line 106, in send_error
{'code': code, 'message': _quote_html(message), 'explain': explain})
NameError: global name '_quote_html' is not defined
So my question is how can I access function outside parent class in module file? In my case from send_error() to _quote_html(). Everythong is imported from BaseHTTPServer.py:
from BaseHTTPServer import *
from <module> import *is generally frowned upon since it pollutes the local namespace and makes it hard to track an item's origin.
