I am reading Data from CSV
file which comes similar to the below matrix/array
b = [[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]]
I would like to change the index of every element greater than 1 to a new row in the arraylist
this will make the above array as below
b = [[1,2],[5,6],[9,10],[3,4],[7,8][11,12]]
what i have done in python (but couldn't get the answer)
b = [[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]]
c = b
rows = len(b)
columns = len(b[0])
c[4].append(1)
count = 3
for i in range(rows):
for j in range(columns):
if i > 1:
for k in columns
list1 =
c.insert(count,list1)
count = count + 1
Why not just split it into two lists, and then recombine them?
new_elements = []
for i in range(len(b)):
if len(b[i]) > 2:
new_elements.append(b[i][2:])
b[i] = b[i][:2]
b.extend(new_elements)
