Write a program that copies one file to another. Prompt the user for the input and output file names.

Ex: If the file input.txt contains:

Mary had a little lamb
Whose fleece was white as snow.
And everywhere that Mary went,
The lamb was sure to go!
the file output.txt will also contain:

Mary had a little lamb
Whose fleece was white as snow.
And everywhere that Mary went,
The lamb was sure to go!
A run of the program is:

Enter input file name: mary.txt
Enter output file name: output.txt

In python please
