Writing to a text file from python list

Question

I am trying to create a text file and write to it from a python list.

Code:

file1 = open("test.txt","w")
test_list = ['hi', 'hello', 'welcome']
for each_ele in test_list:
    file1.write(each_ele+'\n')
file1.close()

Still the file is empty, any suggestions please?

Cannot reproduce the problem. Check if you have write access to the target file/directory. — iBug, Jan 30 '18 at 12:37
you are doing everything right. Check if you are opening correct file when you check for result — Gaur93, Jan 30 '18 at 12:37
Your code works. Maybe you are lookin in the wrong directory? — mrCarnivore, Jan 30 '18 at 12:38

It is recommended to use with when operating with files. This works:

test_list = ['a', 'b']
with open("test.txt","w") as file1:
    for each_ele in test_list:
        file1.write(each_ele+'\n')

Most likely test_list is empty in your case... Or you are looking in a wrong directory for the file...

I suspect you are looking at the right file, Use:

import os
os.getcwd()

to check for your working directory, your created file should be there.

It worked for me, I believe the py file doesn't have required permission, change the owner of the file using chown user:user filename.py and try:

file1 = open("sampletest.txt","w+")

file1 = open("sampletest.txt","w+")
test_list = ['hi', 'hello', 'welcome']
for each_ele in test_list:
    file1.write(each_ele+'\n')
file1.close()

output :

hi hello welcome
