python - More than one arguments for a single keyword -

loanwolf_bank_accounts_length = {     '001': 7,       # banque de montréal     '002': 7,       # scotia     '003': 7,       # rbc     '004': 7 or 11, # td (7 or 11)     '006': 7,       # bnc     '010': 7,       # cibc     '016': 9,       # hsbc     '039': 9,       # banque laurentienne     '614': 10,      # tangerine     '815': 7,       # desjardins     '829': 7,       # desjardins ontario } 

and

def clean_bank_account(self):     bank_account = self.form.cleaned_data.get('bank_account')     bank_transit = self.form.cleaned_data.get('bank_transit')     if bank_account not in (none, ''):         bank = self.form.cleaned_data.get('bank')         if bank not in (none, ''):              # check bank account format specific banks             length = settings.loanwolf_bank_accounts_length.get(bank)             if length:                 if bank_transit not in (none, ''):                     if not bank_account.isnumeric() or length != len(bank_account):                         if bank == '004':                             raise validationerror(                                 _('bank account number must contain 7 or 11 digits') % length  # noqa                             )                         else:                             raise validationerror(                                 _('bank account number must contain %d digits') % length  # noqa                             )                 else:                     raise validationerror(                         _('cannot validate bank account without valid bank transit')  # noqa                     )     return bank_account 

i wanted give more 1 arguments, definitions 004 if length different of 7 or 11, want display bank account number must contain 7 or 11 digits. how pass more 1 arguments keyword?

use list or tuple instead of integer values in dictionary.

loanwolf_bank_accounts_length = {     '001': [7],       # banque de montréal     '002': [7],       # scotia     '003': [7],       # rbc     '004': [7, 11],   # td (7 or 11)     '006': [7],       # bnc     '010': [7],       # cibc     '016': [9],       # hsbc     '039': [9],       # banque laurentienne     '614': [10],      # tangerine     '815': [7],       # desjardins     '829': [7],       # desjardins ontario } 

you need change of logic in clean_bank_account too.
