TypeError: expected str, bytes or os.PathLike object, not TextIOWrapper

I have a list called Text. I want to print the contents of the list into a text file. What should I do?

Answer 1

This is something that works for me:

lst = ['Hello There
', 'How are ya
', 'All good?
']

def save(): 
    text_file = asksaveasfile(title="Select Location", filetypes=(("Text Files", "*.txt"),))
     for line in lst:
         text_file.write(line) # Use str(line) if lst is of integers

The mistake is that asksaveasfile returns a _io.TextIOWrapper object, meaning its same as using open(...) one a file. What you wanted was asksaveasfilename() which will return the path of the object, then:

def save(): 
    text_file = asksaveasfilename(title="Select Location", filetypes=(("Text Files", "*.txt"),))
    with open(text_file, 'w') as f:     
        for line in lst:
            f.write(line) # Use str(line) if list of integers
