Create a new list in a for loop every time necessary

Question

So I am trying to create a new SEPARATE list every time a statement is true in python. Essentially:

for i in range(z):
    if X is true:
        create a new list

There is no way to know how many lists I need, I can try to estimate as I am doing a greedy type algorithm but I am struggling to figure out how iteratively make new separate lists.

`l = []`? Perhaps we could be of more help if you explained what algorithm you were trying to write. — blueteeth, Jan 28 '20 at 08:28

Try doing

myList = []
for i in range(z):
  if X is true:
    lis = []        
    #do something with lis
  myList.append(lis)

If you post exactly what you want to do after creating a new list, then a more efficient answer can be explained.. Based on the provided information, this is all I could come up with.
