write code to print print pi=3.14 with lib SciPy ????

I want to display all constants in the scipy ??

What is output :

import numpy as np
from scipy.sparse import csr_matrix
arr = np.array([0, 0, 0, 0, 0, 1, 1, 0, 2])
print(csr_matrix(arr))

•  (0, 5)    1
    (0, 6)	1
    (0, 8)	2

•  [1 1 2]

• 3

• (1, 2) 	1
    (2, 0)  1
    (2, 2)  2

True or False: Optimizers are a set of procedures defined in SciPy that either find the minimum value of a function, or the root of an equation?

• True

• False

When working with the csgraph modul, what is a correct method to find the shortest path in a graph from one element to another?

• dijkstra()

• bellmann()

• ford()

what is output :

import numpy
speed = [99,86,87,88,111,86,103,87,94,78,77,85,86]
x = numpy.mean(speed) print(x)

y = numpy.median(speed) print(y)

z = stats.mode(speed) print(z)
