How to chunk n segments from a nestled list

I'm trying to chunk 100 lists from a nestled list. I have looked looked through multiple examples on Stack Overflow, but I still cannot get something working correctly.

My primary list is named data_to_insert and it contains other lists. I would like to extract (chunk) 100 lists from the primary nestled list.

How do I accomplish this?

This is my current code, which doesn't work as needed.

def divide_chunks(l, n):
   for i in range(0, len(l), n):
      yield l[i:i + n]

n = 100
x = list(divide_chunks(data_to_insert, 100))

Nestled list example:

data_to_insert = [['item1','item2','item3','item4','item5','item6'],
 ['item1','item2','item3','item4','item5','item6'],
 ['item1','item2','item3','item4','item5','item6'],
 ['item1','item2','item3','item4','item5','item6'],
 ['item1','item2','item3','item4','item5','item6'],
 ...
 [thousands of others lists go here]]

Desired output is another list (sliced_data), which contains 100 lists from the nestled list (data_to_insert).

sliced_data = [['item1','item2','item3','item4','item5','item6'],
 ['item1','item2','item3','item4','item5','item6'], 
 ...
 [98 more lists go here]]

I need to loop through the nestled list, data_to_insert until it's empty.

Solution

You can use random to select 100 random nested lists from your given list.

This will output 3 random nested list from original list,

import random

l = [[1,2], [3,4], [1,1], [2,3], [3,5], [0,0]]
print(random.sample(l, 3))


# output,
[[3, 4], [1, 2], [2, 3]]

If you do not want a list output then replace print(random.sample(l, 3)) with print(*random.sample(l, 3)),

# output,
[1, 2] [2, 3] [1, 1]

If you just want first 100 nested lists then do,

print(l[:100])
