How to write data in to the text file after printing?

Question

I am trying to print the data and store it in a text file. So, Here is the code that I followed.
If I am using this I can not be able to write the output into the text file. However, I am using 'a+' option instead 'w'It is appending the output. But I need the output to be stored only once.
with open('new.txt' , 'w') as file:
file.write(out)
Where out is the output of the previous file
Any suggestions regarding this would be appreciated.

It would be a good idea if you could show us the complete code. Please store it in playground and link it here. I am also not sure what you mean when you are talking about "... previous file...". Thanks!
