Please who can help me.

I have this function:

  def compute_n_1_info(self,cr,uid,payslip,context=None):
       	if tools['int'](payslip.date_from[5:7])==1:
            value = {'assiette_irpp_anuel_reel_n_1': 0.0,
                 'irpp_reel_n_1': 0.0,
                 'cumul_brut_imp_reel_n_1': 0.0,
                 'cumul_retenue_source_n_1': 0.0,
                     }
	else:
            value = {'assiette_irpp_anuel_reel_n_1': 1,
                 'irpp_reel_n_1': 1,
                 'cumul_brut_imp_reel_n_1': 1,
                 'cumul_retenue_source_n_1': 1,
                     }
