Which list comprehension correctly creates a list of even numbers from 0 to 10 (inclusive)?

[x for x in range(11) if x % 2 != 0]

[x for x in range(10) if x % 2 == 0]

[x for x in range(11) if x % 2 == 0]

[x for x in range(11) if x // 2 == 0]

Given the list `words = ['apple', 'banana', 'cherry', 'date']`, which comprehension builds a list of words that start with the letter 'a'?

[w for w in words if w[0] == 'a']

[w for w in words if w.startswith('a')]

[w for w in words if w.endswith('a')]

Which nested list comprehension correctly produces a 3x3 matrix with values 0, 1, 2 in each row?

[[j for i in range(3)] for j in range(3)]

[[i for i in range(3)] for j in range(3)]

[[i for j in range(3)] for i in range(3)]

[[j for j in range(3)] for i in range(3)]

Which nested list comprehension flattens the matrix `matrix = [[1,2],[3,4]]` into a single list `[1,2,3,4]`?

[row for num in matrix for row in num]

[num for num in matrix for row in num]

[[num for num in row] for row in matrix]

[num for row in matrix for num in row]

A data analyst needs to produce a list of all even numbers from 0 to 20, but only those that are also multiples of 3. They want a single, readable line of code. Which list comprehension should they use?

[x for x in range(21) if x % 2 == 0 and x % 3 == 0]

[x for x in range(21) if x % 2 == 0 if x % 3 == 0]

[x for x in range(20) if x % 2 == 0 and x % 3 == 0]

[x for x in range(21) if x % 6 == 0]
