列表理解功能可从一系列数字中查找所有素数？

Question

[x for x in range(1,100) if all(x%y for y in range(2,x))]

Not able to understand how above code is returning correct results, Instead it should be

[x for x in range(1,100) if all(x%y!=0 for y in range(2,x))]

The reason is if all is True if only one of the condition is True .

Answer 1

Non-zero integers are considered truthy in a boolean context, so the code snippets are equivalent.

Note that this algorithm incorrectly classifies 1 as a prime number.
