Split List Based Off A Number Of Items In Python

This function takes a list and an index and returns a list of lists with each one containing the number of items

def split_list(initial_list, split_index):
    return_lists = []
    while initial_list:
        return_lists.append(initial_list[:split_index])
        initial_list = initial_list[split_index:]
    return return_lists


list = ['a', 'b', 'c', 'd', 'e', 'f', 'g']

new_lists = split_list(list, 2)

print(new_lists)

Returns:

[
  ['a', 'b'],
  ['c', 'd'],
  ['e', 'f'], 
  ['g']
]

Here's a basic way to do it with just a single split

def split_list(initial_list, split_index):
    return [
        initial_list[:split_index],
        initial_list[split_index:]
    ]


list = ['a', 'b', 'c', 'd', 'e', 'f', 'g']

new_lists = split_list(list, 2)

print(new_lists)

Returns:

# [
#   ['a', 'b'], 
#   ['c', 'd', 'e', 'f', 'g']
# ]
