如何转换网格：

x,x
x,x

到列表列表？：

[['x', 'x'], ['x', 'x']]

Answer 1

它很简单：

with open(...) as f:
    list_of_lists = [line.strip().split(",") for line in f]
# use list_of_lists

Answer 2

这是获取列表列表的方法：

gridlist = []
f = open('**path/to/file/here**')

for line in f:
    a = line.strip().split(',')
    gridlist.append(a)
print gridlist

Answer 3

创建一个函数来遍历每一行并用逗号分隔它们。

def get_gridas_list(filename):
    # an empty list to store your data
    grid_list = []
    # with is the safest way to open a text document
    with open(filename, 'r') as file:
        # iterate through all the lines in the file
        for line in file:
            #split is a function associated with strings
            # "x,x".split(',') -> ['x', 'x']
            grid_list.append(line.strip().split(','))
    # return the now full list of lists
    return grid_list

Answer 4

使用文件中的readline，然后使用split-method

list = []

line_from_file = '23wda, wa0dw'

parts = line_from_file.split(', ')

list.append([parts[0], parts[1]])

line_from_file = '234f4fda, wa03d2dw'

parts = line_from_file.split(', ')

list.append([parts[0], parts[1]])

print(list)
