List comprehension and string conversion with formatting

[stephen_b]

I'd like to convert a list of floats to a list of strings constrained
to one .1f format. These don't work. Is there a better way?

[".1f" % i for i in l]
or
[(".1f" % i) for i in l]

You need a % in there, chief.

[ "%.1f" % x for x in lst ]

BTW, I took the liberty of making a few style choices, highly
recommended: not to use "i" for floating points ("i" strongly suggests
integer value to many programmers), and not using "l" (the letter ell)
as a name, it can be hard to distinguish from a "1" (the number one).

There's a missing %, this does work...

["%.1f" % i for i in l]

You are so right. Thanks.
