How can I turn a list such as:
data_list = [0,1,2,3,4,5,6,7,8,9]
into a array (I'm using numpy) that looks like:
data_array = [ [0,1] , [2,3] , [4,5] , [6,7] , [8,9] ]
Can I slice segments off the beginning of the list and append them to an empty array?
Thanks
>>> import numpy as np
>>> np.array(data_list).reshape(-1, 2)
array([[0, 1],
[2, 3],
[4, 5],
[6, 7],
[8, 9]])
(The reshape method returns a new "view" on the array; it doesn't copy the data.)
def nest_list(list1,rows, columns):
result=[]
start = 0
end = columns
for i in range(rows):
result.append(list1[start:end])
start +=columns
end += columns
return result
for:
list1=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
nest_list(list1,4,4)
Output:
[[0, 1, 2, 3], [4, 5, 6, 7], [8, 9, 10, 11], [12, 13, 14, 15]]
