Are list comprehensions syntactic sugar for `list(generator expression)` in Python 3?

Are list comprehensions syntactic sugar for `list(generator expression)` in Python 3? In Python 3, is a list comprehension simply syntactic sugar for a generator expression fed into the list function? list e.g. is the following code: squares = [x**2 for x in range(1000)] actually converted in the background into the following? squares = list(x**2 for x in range(1000)) I know the output is identical, and Python 3 fixes the surprising side-effects to surrounding namespaces that list comprehensions had, but in terms of what the CPython interpreter does under the hood, is the former converted to the latter, or are there any difference in how the code gets executed? I found this claim of equivalence in the comments section to this question, and a quick google search showed the same claim being made here. There was also some mention of this in the What's New in Python 3.0 docs, but the wording is somewhat vague: Also note that list comprehensions have different semantics: they ar

The data types varchar and varchar are incompatible in the modulo operator SQL Server

The data types varchar and varchar are incompatible in the modulo operator SQL Server I get this error: The data types varchar and varchar are incompatible in the modulo operator. when running this code ' Number LIKE '%' + @search + '%' '; The number is an integer and this code snippet appears enclosed in ''; due to a dynamic pivot statement. Any ideas how i can run this? thanks Please show a more complete SQL statement. – Gordon Linoff Aug 28 at 10:55 If your percent sign, meant to be around your search parameter, i.e. WHERE Foo LIKE '%bar%' and you get a modulo operator error, you have a quote mismatch somewhere. Read How to Ask and show a Minimal, Complete, and Verifiable example. – CodeCaster Aug 28 at 10:56 WHERE Foo LIKE '%bar%' Could you use an IDE that color codes string literals so that you could see the problem yourself? – Salman A Aug 28 at 11:00 3 Answers 3 Presumably, you have something like thi
