solution offered by Python is to store lists and tuples into arrays. 4.1 Assigning arrays Names for arrays follow the same rules as those defined for scalar variables. We store a list into an array the same way we store a scalar into a scalar variable, by assigning it with =: for a tuple, or for a list.

VECTORS, ARRAYS –USING NUMPY •A NumPy array is a grid of values, all of the same type. The shape of an array is a tuple of integers giving the size of the array along each dimension. •Array Creation import numpy as np a = np.array([1, 2, 3]) # Create a rank 1 array print(a.shape) # Prints "(3,)“. Indicates 3 elements along a dimension.

Example • Python lists are internally organized as arrays of object pointers • Python sets are internally organized as hash-tables • Experiment: • Create a set and a list with the same 100,000 random elements • Then search for the ﬁrst 100,000 elements in the set and the list • Result: List is much slower (timing in sec) • array: 126.1766300201416
