为什么我的程序忽略115行代码

Question

我正在编写一个程序来读取由文件中的符号组成的迷宫，该文件将每个符号存储在一个对象中，然后将该对象存储在一个2D数组中，在从文件中提取符号的位置，然后存储在另一个不同类型的对象中。然而，当它到达应该读取文件并进行比较的部分时，它忽略了代码。我知道这一点，因为我已经注释掉了在数组中存储对象的函数，代码运行并产生相同的输出。这两个类分别称为Position和Maze。

self.maze_map[rows][columns] = position

columns_current = 0

with open(filename, 'r') as f1:
for line in f1:
lines_list.append(line)
for char in line:
chars_list.append(char)
rows_total = len(lines_list)
if (len(lines_list) == 0):
columns_total = 0
elif (len(lines_list) == 1):
columns_total = (len(chars_list)/len(lines_list))
else:
columns_total = (len(chars_list)/len(lines_list)) - 1
index_last_line = rows_total - 1
index_last_char = columns_total - 1
maze_obj = Maze(int(rows_total), int(columns_total))

它没有忽略任何东西。您的文件迭代器已耗尽。

与其尝试多次遍历for line in f1，不如尝试在第一次遍历文件

后使用for line in lines_list

你甚至可以取消缩进chars_list.append(char)之后的每一行，因为你不再需要这个文件了
