Show transcript
There are different modes for opening a file, r (read), w (write) and a (append).
When you open a file in write mode, it creates a new file. If the file already exists then the file will be overwritten.
When you open a file and write to a file in append mode, it will add to the existing contents of the file.
It is good practice to close the file once written to. Some IDEs will not write to a file until it is closed.
