python Cannot write file when import module function

Question

I created a module "test" with these code:

def write_file():
    with open("testw.txt", 'w') as t:
        t.writelines("test ok")
        print(t)

if import from other module and run below code:

import test

test.write_file()

it can print out: <_io.TextIOWrapper name='testw.txt' mode='w' encoding='cp950'> but the file cannot create!

If i run write_file() in test module, it can create the file just fine, how can i write the file while the write file code is import from other module?

Answer 1

Um there are 2 ways you could do it i guess.

First:

Create a different folder called test_module and add the test.py file into the directory. Also ad a blank init.py file to the folder.

so if you do this,

import test_module
test_module.test.write_file()


or...

from test_module import test
test.write_file()

It should probably work

The second way is this

import .test as test
test.write_file()

you could also do this

from .test import write_file
write_file()
