Can I copy/paste Python code?

[ryguy7272]

I'm trying to copy some Python code from a PDF book that I'm reading.  I want to test out the code, and I can copy it, but when I paste it into the Shell, everything is all screwed up because of the indentation. Every time I paste in any kind of code, it seems like everything is immediately left-justified, and then nothing works.

Any idea how to make this work easily?  Without re-typing hundreds of lines of code...

Thanks to all.
