When you redirect stdout to a file that already exists, the existing file will be overwritten by default. This means that any content previously in the file will be lost, and new output sent to stdout will be written to that file instead.
If you want to append to the existing file instead of overwriting it, you can open the file in append mode by using 'a' instead of 'w' when opening the file. Here’s an example:
with redirect_stdout(open('out.txt', 'a')) as file:
print("This will be appended to the existing content.")
In this case, the new output will be added to the end of out.txt without deleting the existing content.
