             if sendrep==True:
                f=open(curdir+sep+self.path)
                self.send_response(200)
                self.send_header('content-type',mimetype)
                self.end_headers()
                self.wfile.write(f.read())
                f.close()
             return
        except IOError:

        log_file = open('logfile.txt', 'w')
        def log_message(self, format, *args):
            self.log_file.write("%s - - [%s] %s %s\n" %(self.client_address[0],self.log_date_time_string(),curdir+sep+self.path,format%args))
class ThreadedHTTPServer(ThreadingMixIn, HTTPServer):
     """Handle requests in a separate thread."""
print("asb")
try:
     server=ThreadedHTTPServer(('127.0.0.1',8080),myhandler)
     server.serve_forever()
except KeyboardInterrupt:
if KeyboardInterrupt:
    print('shut down the server')
    server.socket.close()

Two things:

1. there is sendrep-True in several lines which is not a syntax error, but a useless statement. It should be sendrep = True (equals not minus).

2. You also open your file in binary mode: f=open(curdir+sep+self.path, "br") otherwise you will get a TypeError: a bytes-like object is required, not 'str'
