Funktion anhängen, nicht in der Lage, das richtige Ergebnis zu erhalten

Question

Ich habe das folgende Problem.

for som in range(0,len(var)):           # For each number in var (the sequence) 
     if len(PeriodNumbers[som]) != 2:         # When the length of PeriodNumbers is not 2 (2 meaning that there's a column falling in 2 different periods) 
      TempColNrsperPeriod.append(var[som])       # When the if statement is valid we append the column from the sequence. 
      #print TempColNrsperPeriod 
     else:                # When the if statement is false (meaning that lenght is 2): 
      TempColNrsperPeriod.append(var[som])       # We append the current column to the temp list 
      ColNrsperPeriod.append([TempColNrsperPeriod])     # Appending the Temp list to the ColNrsperPeriod list 
     # I do not set the TempcolNrsperPeriod to 0, since I want the next appending to be the cummulative of all columns up until and including the current period. 

var = [42, 30, 45, 61, 62, 80, 81, 101, 83, 66, 49, 24, 15, 25, 52, 39, 53, 68, 54, 41, 29, 28, 17, 26, 51, 50, 48, 34, 64, 65, 84, 67, 35, 47, 33, 63, 82, 100, 119, 141, 140, 115, 137, 136, 113, 159, 183, 213, 185, 158, 209, 231, 208, 230, 207, 206, 154, 178, 126, 104, 105, 129, 130, 155, 179, 153, 106, 127, 177, 151, 152, 128, 107, 108, 89, 90, 91, 111, 157, 131, 156, 182, 212, 160, 134, 133, 110, 109, 132, 92, 93, 74, 72, 73, 56, 57, 58, 75, 76, 94, 112, 135, 161, 186, 162, 138, 114, 95, 97, 77, 60, 43, 44, 31, 32, 46, 78, 116, 98, 118, 120, 99, 117, 139, 163, 187, 251, 260, 252, 259, 258, 266, 253, 222, 173, 202, 172, 171, 197, 238, 237, 219, 195, 167, 217, 193, 164, 216, 235, 246, 215, 191, 192, 233, 232, 214, 165, 194, 166, 142, 168, 198, 236, 248, 250, 249, 257, 263, 247, 234, 218, 196, 169, 143, 144, 121, 148, 146, 170, 199, 223, 240, 241, 242, 201, 203, 174, 175, 204, 228, 176, 205, 245, 244, 254, 262, 261, 239, 221, 220, 79, 59, 96, 103, 124, 147, 123, 125, 150, 149, 200, 224, 225, 226, 243, 227, 255, 190, 189, 188, 86, 87, 70, 71, 88, 38, 37, 36, 23, 14, 8, 16, 9, 10, 27, 40, 69, 85, 102, 20, 19, 18, 11, 3, 6, 12, 4, 5, 13, 7, 2, 1, 55, 184, 210, 211, 181, 180, 229, 264, 265, 256, 122, 145, 22, 21]

Was würde ich erreichen möge (für jede Periode von dem periodnumbers, ich mochte die Menge aller Werte haben, bis dahin und whitin dieser Zeit. Und diese Ergebnisse zu ColNrsperPeriod hängen, als ich versuchte zeigte unten):

ColNrsperPeriod = [[42, 30, 45],[42, 30, 45, 61, 62, 80, 81, 101, 83],[...... 

Aus irgendeinem Grund kann ich es nicht, zu arbeiten und sehen, nicht was das Problem ist.

Bitte lassen Sie mich wissen, was ich tun soll, um das zu beheben. Ich danke dir sehr.

Answer 1

ColNrsperPeriod.append([TempColNrsperPeriod]) - ColNrsperPeriod würde enthält N Kopien der gleichen Liste. Listen sind veränderbar, sodass Änderungen von den nächsten Interaktionen in die zuvor angefügte Liste übernommen werden.

Wenn Sie den aktuellen Status der Liste anhängen möchten, müssen Sie eine Kopie erstellen. Versuchen Sie ColNrsperPeriod.append(TempColNrsperPeriod[:]).
