for mistake #1 >>> import random >>> def foo(bar={}): ... bar[random.randint(1,100)]="hii" ... print bar ... >>> foo() {76: 'hii'} >>> foo() {76: 'hii', 85: 'hii'} >>> foo() {76: 'hii', 85: 'hii', 30: 'hii'} >>> foo() {1: 'hii'...
NumPy also contains a number of useful methods for reading text and binary data files, fitting polynomial functions, many mathematical functions (sine, cosine, square root, and so on), and generating random numbers. The performance-sensitive parts of NumPy are all written in the C language, so...

What code would create an array of 10 random numbers between zero and one? Show Solution np.random.rand(10) # Example output: # array([0.83698711, 0.24264316, 0.30675551, 0.63795295, 0.87011717, # 0.27054306, 0.65159876, 0.49426323, 0.68323172, 0.69278983]) Creating...

changed methods ofnumpy.random.Generatorthat are used bycopyandpickle. To get a copy of a numpyGeneratorwith independent state, you must usedeepcopynow, instead ofcopy This PR also changed the return value ofGenerator.__getstate__()toNone. To get the state now, you must useGenerator.bit_...
_state : int, RandomState instance or None, optional (default=None) If int, random_state is the seed used by the random number generator; If RandomState instance, random_state is the random number generator; If None, the random number generator is the RandomState instance used by np.random....
and hashCode methods. However, it has broken the contract, because hashCode returns random values for the same object every time it’s called. The following code will most likely not find a boat named “Enterprise” in the hashset, despite the fact that we added that kind of boat earlier:...
