Python: Chunk a given list into smaller lists of a specified size
Python List: Exercise - 232 with Solution
Write a Python program to chunk a given list into smaller lists of a specified size.
- Use list() and range() to create a list of the desired size.
- Use map() on the list and fill it with splices of the given list.
- Finally, return the created list.
Sample Solution:
Python Code:
# Import the 'ceil' function from the 'math' module.
from math import ceil
# Define a function 'chunk_list' that takes a list 'lst' and an integer 'size' as input.
def chunk_list(lst, size):
# Use list comprehensions to create a list of chunks, where each chunk has 'size' elements.
# The 'range' function is used to generate the indices for splitting the list.
return list(map(lambda x: lst[x * size:x * size + size], # Lambda function to get each chunk.
list(range(ceil(len(lst) / size))))) # Calculate the number of chunks needed and generate indices.
# Call the 'chunk_list' function with an example list and chunk size.
print(chunk_list([1, 2, 3, 4, 5, 6, 7, 8], 3))
Sample Output:
[[1, 2, 3], [4, 5, 6], [7, 8]]
Flowchart:
Python Code Editor:
Previous: Write a Python program to split values into two groups, based on the result of the given filter list.
Next: Write a Python program to chunk a given list into n smaller lists.
