如何从导入的 csv 文件中删除单引号到列表中？
我将列表导出到 csv 文件中，如下所示：
file = open('all_states.csv', 'w+', newline='')
# writing the data into the file
with file:
write = csv.writer(file)
write.writerows(all_states)
从另一个脚本中，我将 csv 文件导入为：
with open('all_states.csv') as file:
reader = csv.reader(file)
states = list(reader)
file.close()
导出的原始数据是：
exp_data = [
[[0], [[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]], [0, 0, 1]],
[[0], [[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]], [-1, 0, 0]],
[[0], [[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]], [0, -1, 0]]
]
但是当我导入时，我得到了一些我想删除的单引号。
impo_data = [
['[0]', '[[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]]', '[0, 0, 1]'],
['[0]', '[[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]]', '[-1, 0, 0]'],
['[0]', '[[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]]', '[0, -1, 0]']
]
如何在导出或导入时删除引号？
I export a list into a csv file as:
file = open('all_states.csv', 'w+', newline='')
# writing the data into the file
with file:
write = csv.writer(file)
write.writerows(all_states)
And from another script I import the csv file as:
with open('all_states.csv') as file:
reader = csv.reader(file)
states = list(reader)
file.close()
The original data that was exported was:
exp_data = [
[[0], [[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]], [0, 0, 1]],
[[0], [[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]], [-1, 0, 0]],
[[0], [[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]], [0, -1, 0]]
]
But when I imported I get some single quotes that I'd like to remove.
impo_data = [
['[0]', '[[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]]', '[0, 0, 1]'],
['[0]', '[[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]]', '[-1, 0, 0]'],
['[0]', '[[1, 0, 0], [1, 0, 0], [0, 1, 0], [1, 0, 0], [1, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 0], [0, 1, 0]]', '[0, -1, 0]']
]
How can I remove the quotes when exporting or once imported?

问题是您的 CSV 文件被作为字符串读取，而您希望将其视为字符串而不是字符串。您的项目看起来都是 JSON，因此只需通过 json.loads 运行它们即可。
The issue is that your CSV file is read as a string, while you want to process it as if it is not. Your items look like they are all JSON, so just run them through
json.loads.据我所知，csv格式的引用没问题。但如果您想删除引号，可以尝试以下操作。导入 csv 文件时，定义 quotechar：
As far as I know, quotations are fine with csv format. But if you want to remove the quotes, you can try the following. While importing the csv file, define the quotechar:
