How to create 2d array with numpy random.choice for every rows?

Question

I\'m trying to create a 2d array (which is a six column and lots of rows) with numpy random choice with unique values between 1 and 50 for every row not all of the array

Answer 1

You can create each row by itself and then stack them.

np.stack([np.random.choice(np.arange(1,50),size=6,replace=False) for i in range(100)])
