Question

I need to know if it is possible to save a python list as a numPy array.

Answer 1

If you look here, it might tell you what you need to know.

Basically, you can create an array from a sequence.

import numpy as np
a = np.array( [2,3,4] )

Or from a sequence of sequences.

import numpy as np
a = np.array( [[2,3,4], [3,4,5]] )

Answer 2

I suppose, you mean converting a list into a numpy array? Then,

import numpy as np

# b is some list, then ...    
a = np.array(b).reshape(lengthDim0, lengthDim1);

gives you a as an array of list b in the shape given in reshape.

Answer 3

import numpy as np 

... ## other code

some list comprehension

t=[nodel[ nodenext[i][j] ] for j in idx]
            #for each link, find the node lables 
            #t is the list of node labels 

Convert the list to a numpy array using the array method specified in the numpy library.

t=np.array(t)
