Python post a .xlsx file via Requests

Question

I'm trying to upload a xlsx file to a server using the following code and I'm getting a 409 error. I think its related to the fact there is an existing file on the server with the same name that I'm trying to post? I basicly just want to overwrite the file if it exists?

If I delete the file on the server then the next time this script runs it does post the file just fine? Thanks for any help
