Question

8. Write a function that changes the extension in the file name to the specified one (for example,
on '.bak'). The function takes two parameters: the file name and the extension. Mind you
that in the original name the extension may be empty.

Answer 1

If you just want to change the extension you can use the os.splittext method and split it at the dot. After that you save each part in two variables and then just save as var1 + your wished extension
