Creating Arrays

import numpy as np

a = np.array([1, 2, 3, 4, 5])
z = np.zeros(5)
o = np.ones((2, 3))          # a 2x3 array of ones
r = np.arange(0, 10, 2)      # like range(), but returns an array
lin = np.linspace(0, 10, 5)  # 5 evenly spaced points from 0 to 10

print(a)
print(z)
print(o)
print(r)
print(lin)

[[1. 1. 1.]

[0 2 4 6 8]
[ 0.   2.5  5.   7.5 10. ]
