Hi,
I'm using decos for the first time.I want to check the input and then call a
function in a class.
I'm pasting the code:
def check_input_sanity(self,rover_input):
'''Check the input from client'''
def _check(fn):
def _inner(rover_input):
if
rover_input[0].upper().replace('L','').replace('R').replace('M') == '' and
rover_input[1].upper() in ['N','S','E','W']:
print 'Input is sane'
fn()
return _inner
return _check
@check_input_sanity([self.origorient,self.direction_str,self.init_loc])
def tell_coord_from_path(self):
'''Gives the final co-ordinate and the direction untill it falls
off/reaches.'''
pdir = self.origorient #Present direction
here the vars : self.origorient,self.direction_str,self.init_loc are the ones I
would like to check for sanity.
But I get an error:
Traceback (most recent call last):
File "tw.py", line 5, in <module>
import sys,os,robo
File "C:\Python25\thought\robo.py", line 30, in <module>
class robo_actions(robo):
File "C:\Python25\thought\robo.py", line 58, in robo_actions
@check_input_sanity([self.origorient,self.direction_str,self.init_loc])
NameError: name 'self' is not defined
Why is this so? aren't they to be referred to by self with in a class as they
are attributes of the object ?
