The following code all creates unnecessary list comprehensions
a = all([i is not None for i in range(10)])
b = tuple([i * 2 for i in range(10)])
c = sum([i * 2 for i in range(10)])
d = ",".join([str(i * 2) for i in range(10)])ruff will only suggest changes on the first line:

= help: Remove unnecessary list comprehension
However all of these are unnecessary list comprehensions. It ought to be able to identify them all. For one, the docs suggest that sum is covered, but from the above, it appears to not fully be.
