Hello, there is something I don't understand about list comprehensions.
I understand how does this work: print [[y for x in range(8)] for y in range(8)] However I don't understand why this one works: print [[y for y in range(8)] for y in range(8)] In this second example I have one loop nested in another. Both loops uses the same variable - y. How is it that those loops do not conflict with each other? For a moment I thought that maybe list comprehension has its own scope, but it doesn't seem to be so: print [[y for y in range(8)] for y in range(8)] print y Does anybody understand it? -- http://mail.python.org/mailman/listinfo/python-list
