Exclamation Error in Chaptor 4

Page 60, Creating and Accessing Single-Dimension Arrays,
MyList = sys.path
The description in the paragraph after this statement is wrong. Python/IronPython does not make a copy of the content of a list. Instead, the memory reference of the original list is assigned to the new variable. If you try to change the content in MyList, sys.path also got changed. I have tested and conformed this on my machine, running IronPython 2.6.2 on .Net 4.0

Smile Error in Chapter 4

I promise to check this problem out. You may very well be correct because it sounds like the way IronPython would do things. Thanks for pointing the problem out. Of course, errors do creep into even the best of books . In fact, I've written a post on my blog about it at http://blog.johnmuellerbooks.com/201...n-writing.aspx. In the meantime, I hope you're enjoying the book and will let me know if you discover any other potential problems with it. Make sure you keep up with updates about the book by reviewing my blog. Let me know if you have any questions about the book at mailto:John@JohnMuellerBooks.com.
