Printing empty list? - hhydration - Oct-28-2020 def kasinski(text): trigraphs=[] distances=[] for trigraph in range (len(text)-2): newtrigraph= text[trigraph:trigraph+3] if newtrigraph in trigraphs: distances.append(trigraph-(text.index(newtrigraph))) else: trigraphs.append(newtrigraph) trigraphs.append(trigraph) return distancesCan anyone identify why this function is returning "[]"? I am printing with the string "UZRZEGNJENVLISEXRHLYPYEGTESBJHJCSBPTGDYFXXBHEEIFTCCHVRKPNHWXPCTUQTGDJHTBIPRFEMJCNHVTCFSAIIJENREGSALHXHWZWRZXGTTVWGDHTEYXISAGQTCJPRSIAPTUMGZALHXHHSOHPWCZLBRZTCBRGHCDIQIKTOAAEFTOPYEGTENRAIALNRXLPCEPYKGPNGPRQPIAKWXDCBZXGPDNRWXEIFZXGJLVOXAJTUEMBLNLQHGPWVPEQPIAXATYENVYJEUEI"(this string does contain repeated trigraphs) RE: Printing empty list? - deanhystad - Oct-28-2020 Don't double post RE: Printing empty list? - Atekka - Oct-28-2020 If the way your code is indented is the way it is in your code snippet, you just have to indent the lines after your for loop as shown below. Hope that helps =] def kasinski(text): trigraphs=[] distances=[] for trigraph in range (len(text)-2): newtrigraph= text[trigraph:trigraph+3] if newtrigraph in trigraphs: distances.append(trigraph-(text.index(newtrigraph))) else: trigraphs.append(newtrigraph) trigraphs.append(trigraph) return distances |
