Miguel Brito Great Miguel, thank you! I find with a friend this function, using the levenshtein distance: ListEtats = [ 'Birmanie' , 'Biélorussie' , 'Bolivie' , 'Brunei' , 'Burkina' , 'Bélize' , 'Cap-Vert' , 'Centrafrique' , 'Chine' , 'Corée du Nord' , 'Corée du Sud' , 'Guatémala' , 'Guinée Bissao' , 'Irak' , 'Iran' , 'Kirghizstan' , 'Kosovo' , 'Kénya' , 'Laos' , 'Liechtenstein' , 'Lésotho' , 'Micronésie' , 'Moldavie' , 'Monaco' , 'Niue' , 'Royaume-Uni' , 'Russie' , 'Saint-Christophe et Niévès' , 'Saint Marin' , 'Saint Vincent et les Grenadines' , 'Salomon' , 'Salvador' , 'Syrie' , 'Tanzanie' , 'Timor oriental' , 'Vatican' , 'Vietnam' , 'Vénézuéla' , 'Zimbabwé' , 'États Unis' ] ListZones = [ 'Belize' , 'Bermudes' , 'Bolivie État plurinational de' , 'Brunéi Darussalam' , 'Burkina Faso' , 'Bélarus' , 'Cabo Verde' , 'Chine RAS de Hong Kong' , 'Chine RAS de Macao' , 'Chine Taiwan Province de' , 'Chine continentale' , 'El Salvador' , 'Fédération de Russie' , 'Groenland' , 'Guatemala' , 'Guinée Bissau' , 'Iran République islamique d' , 'Iraq' , 'Kenya' , 'Kirghizistan' , 'Lesotho' , 'Micronésie États fédérés de' , 'Myanmar' , 'Nioué' , 'Nouvelle Calédonie' , 'Palestine' , 'Polynésie française' , 'Porto Rico' , 'Royaume Uni de Grande-Bretagne et d Irlande du Nord' , 'République arabe syrienne' , 'République centrafricaine' , 'République de Corée' , 'République de Moldova' , 'République démocratique populaire lao' , 'République populaire démocratique de Corée' , 'République Unie de Tanzanie' , 'Saint Kitts et Nevis' , 'Saint Vincent et les Grenadines' , 'Samoa américaines' , 'Timor Leste' , 'Tokélaou' , 'Venezuela République bolivarienne du' , 'Viet Nam' , 'Zimbabwe' , 'États Unis d Amérique' , 'Îles Salomon' ] import jellyfish def compareList ( list1, list2 ): dict = {} for item1 in list1: for item2 in list2: current_leven = jellyfish.jaro_distance(item1, item2) if item1 not in dict or current_leven > jellyfish.jaro_distance(item1, dict[item1][ 0 ]): dict[item1] = (item2, current_leven) return dict compareList(ListEtats, ListZones) This is good but i think i need to optimise this one by applying your method in a second argument. Thank you again for your help!

Hi thank you for all! I'm begin to Python and i'm trying to make a function, with a condition that finds a row of characters following, between two list of words. I search something like this: List1 = [ 'Birmanie' , 'Biélorussie' , 'Bolivie' , 'Brunei' , 'Burkina' , 'Bélize' , 'Cap-Vert' ] List2 = [ 'Belize' , 'Bermudes' , 'Bolivie (État plurinational de)' , 'Brunéi Darussalam' , 'Burkina Faso' , 'Bélarus' , 'Cabo Verde' ] def matchingword(number_of_character_following = 3 ) for number_of_characters_in_a_row in list1: if number_of_characters_in_a_row in list2: return possible_matching_words in [] else : return no_matching_words in [] My result should be: possible_matching_words = ['Biélo rus sie':'Béla rus ', 'Biélo rus sie':'Brunéi Da rus salam', ' Bol ivie':' Bol ivie (État plurinational de)', ' Bru nei':' Bru néi Darussalam', ' Bur kina':' Bur kina Faso', 'Cap- Ver t':'Cabo Ver de'] How can i do please?
