What will this code do?
import numpy as np
A = np.random.randint(1, 100, size=(5, 5))
B = A.copy()
B[:, [0, -1]] = B[:, [-1, 0]]
d = lambda x: round(np.linalg.det(x))
print(d(A) + d(B))
What will this code do?
"hello" * 0 is '' * 10
What will this code do?
True + ~False
What will this code do?
None or False and True
What will this code do?
bin(2**2) == bin(2**3 >> 1),  bin(2**2) is bin(2**3 >> 1)
Given code
class C: pass
class D (C): __slots__ = ['a']
X = D()
X.a = 1
print(hasattr(X, '__dict__'))

output - True
What should be written in class C instead of 'pass' so that the output is False?
