Speaking of which, I note that there is a pop for lists but no shift.
Is there a Python idiom for this or is it just

Ummm...that doesn't do what I asked.
pop is a linguistic idiom for
(val, mylist) = (mylist[-1], mylist[0:-1])
No, actually, not quite.
From the docs:
s.pop([i]) same as x = s[i]; del s[i]; return x
so val = mylist.pop(0

This must be simple, but for the life of me I can't figure out how to
delete an entry from a dictionary. For example,
meals = {}
meals['breakfast'] = 'slimfast'
meals['lunch'] = 'slimfast'
meals['dinner'] = 'something sensible'
How do I
meals.pop(key) will do it.
Example:
meals = {}
meals['breakfast'] = 'slimfast'
meals['lunch'] = 'slimfast'
meals['dinner'] = 'something sensible'
meals
{'lunch': 'slimfast', 'breakfast': 'slimfast', 'dinner': 'something sensible'}
meals.pop(breakfast)
'slimfast'
meals
{'lunch': 'slimfast',
