Algorithm

  1. Input:

    • lst: The input list to be split.
    • chunk_size: The size of each chunk.

  2. Validation:

    • Check if chunk_size is greater than 0. If not, raise a ValueError.

  3. Calculate Number of Chunks:

    • Calculate num_chunks using the formula: (len(lst) + chunk_size - 1) // chunk_size.

  4. Create Chunks:

    • Use list comprehension to create chunks by iterating over the range of num_chunks.
    • Each chunk is obtained using slicing: lst[i * chunk_size:(i + 1) * chunk_size].

  5. Output:

    • Return the list of chunks (chunks).

 

Code Examples

#1 Code Example- Python Programing Using yield

Code - Python Programming

def split(list_a, chunk_size):

  for i in range(0, len(list_a), chunk_size):
    yield list_a[i:i + chunk_size]

chunk_size = 2
my_list = [1,2,3,4,5,6,7,8,9]
print(list(split(my_list, chunk_size)))
