I'd like to move following books to specified `DirHTML` directory.

```
books = ['HTML-Head First HTML and CSS - 2nd Ed.pdf',
 'HTML and CSS - Design and Build Websites - Jon Duckett - November 2011.pdf',
 "Murach's HTML5 and CSS3 3rd Edition (2015).pdf",
 'HTML5-cheat-sheet.pdf']

```

Easily they can be moved to `DirHTML` with codes:

```
import shutil
for book in books:
    shutil.move(book, 'DirHTML')

```

When I tried

```
map(shutil.move, books, 'DirHTML')

```

There's no files moved.
How to enable the code working?
