Save a list to a .txt file

Question

Is there a function in python that allows us to save a list in a txt file and keep its format?

If I have the list:

values = [\'1\',\'2\',\'3\']


        

Answer 1

Try this, if it helps you

values = ['1', '2', '3']

with open("file.txt", "w") as output:
    output.write(str(values))

Answer 2

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')

Answer 3

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.txt', '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.txt', 'rb') as fp:
    list_1 = pickle.load(fp)
