Quiz 6.1

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, 2) 1

  (2, 0) 1

  (2, 2) 2

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()

a ="4";

b ="2";

print(a + b);

what is the output of this code?

a = 9

b = 5

print(a>b and 4>7)

what is the output of this code?

l = [2,4,6,8]
for i in range(len(l)):
print(2)

l = [2,4,6,8]
for i in range(len(l)):
print(l.pop())

l = [2,4,6,8]
l[0]=100
l.remove(100)
print(l[0])
