Python类IndexError

Question

我写了这个类来编织两行。

class CoordinatRow(object):

def __init__(self):
    self.coordinaterow = []

def add_coordinaterow(self, coordinate):
    self.coordinaterow.append(coordinate)    


def weave(self,other):
    lijst = []
    for i in range(len(self.coordinaterow)):
        lijst.append(self.coordinaterow[i])
        lijst.append(other.coordinaterow[i]) 
    self.coordinaterow = lijst
    return self.coordinaterow

我将坐标添加到对象中：

def process_row(line):                                 
  temp_coordinate_row = CoordinatRow()
  rij = line.split()
  for coordinate in rij:
     coor = process_coordinate(coordinate)
     temp_coordinate_row.add_coordinaterow(coor)
  return temp_coordinate_row

我想通过这样做来添加2行：

def split_and_add(invoer):                             
    rij = invoer.split('=')
    rows = []
    for line in rij:
        rows.append(process_row(line))
    return rows


bestand = file_input()
rows = split_and_add(bestand)
for row in range(0,len(rows)-1):
    rows[row].weave(rows[row+1])

但是我得到了以下错误：

rows[row].weave(rows[row+1])  
lijst.append(other.coordinaterow[i]) 
IndexError: list index out of range

我该如何解决这个问题？

Answer 1

你可以这样做来解决它：

for i in range(len(self.coordinaterow)):
    lijst.append(self.coordinaterow[i])
    try:
        lijst.append(other.coordinaterow[i])
    except IndexError:
        pass
