Interesting. I learned about Python on comp.lang.perl, but that was over 
a decade ago.

This list really has very little other-language bashing.

I forget the exact question you asked, but this list is not the doc. The 
doc section on dicts gives dict(list_of_key_value_pairs) as the one true 
way, given such an input. The Perl way cannot be clearer and can only be 
shorted if it uses something shorter that dict().

If the list is a flat list of alternating keys and values, then yes, 
they must be paired, and there are several ways to do that, partly 
depending on the exact specifications, including allowed input and how 
an odd key left over should be treated. In any case, unpaired keys and 
values strikes me as an unusual input format for a dict. They typically 
would have been paired as some point and in Python, should not need to 
be unpaired.
