Python List and Nested List Assessment

What will be the output of the following list comprehension? numbers = [1, 2, 3, 4, 5] squares = [x**2 for x in numbers]

• [1, 4, 9, 16, 25]

• [2, 4, 6, 8, 10]

• [1, 2, 3, 4, 5]

• [2, 4, 8, 16, 25]

Which list comprehension creates a list of even numbers from 1 to 10?

• [x for x in range(1, 11) if x % 2 == 0]

• [x for x in range(1, 11) if x % 2 != 0]

• [x for x in range(2, 11, 2)]

• [x * 2 for x in range(1, 6)]

Which list comprehension will convert all strings to uppercase?

• [str.upper() for str in words]

• [str.upper for str in words]

• [str.upper(x) for x in words]

• [x.upper() for x in words]

What will be the output of this list comprehension? [x*5 for x in [1,2,3]]

• [5,1,2,3]

• [1,2,3,1,2,3,1,2,3,1,2,3,1,2,3]

• [[5,10,15]]

• [5,10,15]

What's the output of this list comprehension with conditional? [x if x > 2 else 0 for x in [1,2,3,4]]

• [1, 2, 3, 4]

• [0, 0, 3, 4]

• [0, 2, 3, 4]

• [1, 0, 3, 4]

Which list comprehension filters out non-numeric strings?

• [x for x in ['1', 'a', '2', 'b'] if x.isnumeric()]

• [x for x in ['1', 'a', '2', 'b'] if isinstance(x, int)]

• [x for x in ['1', 'a', '2', 'b'] if type(x) == int]

• [x for x in ['1', 'a', '2', 'b'] if x.isdigit]

Which list comprehension creates a list of vowels from a string?

• [x for x in "hello world" if x in ['a','e','i','o','u']]

• [x if x in 'aeiou' else '' for x in "hello world"]

• [x for x in "hello world" where x in 'aeiou']

• ['aeiou' for x in "hello world"]

How do you create a list of even squares using list comprehension?

• [x2 for x in range(10) if x2 % 2 == 0]

• [x2 for x in range(10) if x % 2 == 0]

• [x for x in range(10) if x2 % 2 == 0]

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

What's wrong with this list comprehension? [print(x) for x in range(5)]

• print() cannot be used in list comprehension

• Nothing is wrong, but it's not a good practice

• The syntax is incorrect

• range() cannot be used in list comprehension

What's the output of this conditional list comprehension? [x if x < 3 else 10 for x in range(5)]

• [0, 1, 2, 3, 4]

• [0, 1, 2, 10, 10]

• [10, 10, 10, 3, 4]

• [0, 1, 2, None, None]
