Where in the docs would you put it and what would
Just as a note - you are not the only person caught out by this - it is a
very common slip.
I wonder whether it would be worth adding a more explicit line about this
in the Python Docs?

No, a dict is not a sequence. But it is a container: all its items
remain available and can be retrieved again and again, and you can
interrogate whether a value is one of the items in that container.

Hi All
I have a code that reads a csv file via DictReader. I ran into a peculiar
problem. The python interpreter ignores the 2nd code. That is if I put the
reader iterator 1st, like the code below, the enumerate code is ignored; if
I put the enumerate code 1st, the reader code is ignored. I am
