There are a few similar questions to this one but not exactly the same:
I want to dynamically decrease a given input array or list of lists. For example:
matrix = [[0,1,2], [3,4,5],[6,7,8]]
Starting at 0 I need to iterate through and remove the final index - the iterative. So the output I would like to store in a new list is:
#output
[0,1,2], ,[3,4], [6]]
[0,1,2], ,[3,4], [6]] ==> which then flattens to [0,1,2,3,4,6]
Here's what I'm currently going after:
def get_list(matrix, stop_index):
temp = []
for i in range(0, stop_index):
for m in matrix:
temp.append(matrix[0:stop_index])
outside_list.append(temp)
return outside_list
I believe I am seeing well my over reliance on packages and libraries, so I am really trying to do this without outside packages or imports
Thank you for any help! I don't forget to green check mark.
