Here is a small list of things that want to be done (and natural ways to
perform them)
1. pair items in the lists (using list comprehension),
2. format the pairs (using an f-string),
3. separate the pairs with commas (using join), and
4. incorporate surrounding "foo" "bar" text. (using an f-string)
It would be possible to have
print(f"foo {', '.join(f'{first} {second}' for first, second in zip(l1,
l2))} bar")
But I find nested f-strings to be confusing, and avoid them. This is a
case where I actually prefer format.
print("foo {} bar".format(
', '.join(f'{first} {second}' for first, second in zip(l1, l2))
))
It's still a one-liner, but it's a one liner that I find easier to
parse. Or perhaps I would explicitly construct the string first and then
use it?
innerstr = ', '.join(f'{first} {second} for first, second in zip(l1, l2))
print(f"foo {innerstr} bar")
These ideas are what feel natural to me.
