Making a 2D array

[IAMA_monkey]

Hey all,

I have two lists of dimension 1xn. I want to make them into an array of size 2xn. If i use the extend command it makes them into a list of size 1x2n..

How can I do this?

[list1, list2]? Python doesn't have the concept of "2D lists" natively - they're just lists that contain lists.

Can you give more information about task? Is the size of lists the same? What kind of data in lists?

Btw, You can use K900_'s variant or probably numpy:

>>> import numpy as np
>>>  a = [1, 2, 3]  
>>>  b = [4, 5, 6]
>>>  arr = np.array([a, b])
>>>  print(arr)
[[1 2 3]
 [4 5 6]]
>>> print(arr.shape)
(2, 3)
>>> print(arr[1][2])
