Save a list to a .txt file
You can use inbuilt library pickle
This library allows you to save any object in python to a file
This library will maintain the format as well
import pickle
with open('/content/list_1.ob', 'wb') as fp:
pickle.dump(list_1, fp)
you can also read the list back as an object using same library
with open ('/content/list_1.ob', 'rb') as fp:
list_1 = pickle.load(fp)
NOTE:: File can have any extension you are comfortable with. These files are binary and are not supposed to be viewed manually.
reference : Writing a list to a file with Python
If you have more then 1 dimension array
with open("file.txt", 'w') as output:
for row in values:
output.write(str(row) + '\n')
Code to write without '[' and ']'
with open("file.txt", 'w') as file:
for row in values:
s = " ".join(map(str, row))
file.write(s+'\n')
Try this, if it helps you
values = ['1', '2', '3']
with open("file.txt", "w") as output:
output.write(str(values))
