The np.array_split() function splits an array into multiple sub-arrays. Unlike np.split(), it allows splitting an array into sections of unequal size if the division is not exact.
NumPy Array Splitting
Split a single array into multiple sub-arrays using array_split.
Key Takeaways: NumPy Array Splitting
Mastering NumPy Array Splitting helps you write clean and reliable NumPy code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.
NumPy Array Splitting Code Example
NumPyimport numpy as np
arr = np.arange(1, 10)
parts = np.array_split(arr, 3)
for idx, p in enumerate(parts):
print(f"Chunk {idx + 1}:", p)
Output
Chunk 1: [1 2 3] Chunk 2: [4 5 6] Chunk 3: [7 8 9]
