Save a list to a .txt file
提问by Luis Ramon Ramirez Rodriguez
Is there a function in python that allows us to save a list in a txt file and keep its format?
python中是否有一个函数可以让我们将列表保存在txt文件中并保持其格式？
If I have the list:

values = ['1','2','3']
can I save it to a file that contains:
我可以将其保存到包含以下内容的文件中吗？
'['1','2','3']'
So far I print parts of the list in the terminal and copy those in to a txt file.

If you have more then 1 dimension array
如果你有超过一维数组
with open("file.txt", 'w') as output:
for row in values:
output.write(str(row) + '\n')

You can use inbuilt library pickle
您可以使用内置库泡菜
This library allows you to save any object in python to a file
这个库允许你将python中的任何对象保存到一个文件中
This library will maintain the format as well
该库也将保持格式
import pickle
with open('/content/list_1.txt', 'wb') as fp:
pickle.dump(list_1, fp)
you can also read the list back as an object using same library
您还可以使用相同的库将列表作为对象读回
with open ('/content/list_1.txt', 'rb') as fp:
list_1 = pickle.load(fp)
