NameError: name 'rand' is not defined

[Truman]

From the book...
We'll start by creating a random set of 10 points on a two-dimensional plane. Using the standard convention, we'll arrange these in a 10×2 array

import numpy as np
X = rand.rand(10, 2)
print(X)

Error:

Any idea how to define this second .rand?

[buran]

In[9] rand = np.random.RandomState(42)

so, your code would be

import numpy as np
rand = np.random.RandomState(42)
X = rand.rand(10, 2)
print(X)

Output:
[[0.37454012 0.95071431]

Yeah, it makes sense although number 42 in parenthesis is still a mystery.

[buran]

Note, that is if you want the same seed 42 as in the example code

[buran]

number 42 in parenthesis is still a mystery.

You know, 42 - The Answer to the Ultimate Question of Life, The Universe, and Everything.
I am sure they deliberately choose it as seed

[Truman]

By the way, is there a chance that you also take a look at the topic "Computing the distance between each pair of points". These double colons are still making me headache.

Yeah, I'll have to ask my numerologist what 42 represents...

The Hitchhiker's Guide to the Galaxy had some good parts and some not that good. Anyway, the author was an atheist so I don't think that I can get those answers that I need from him.
