📌 NumPy — Creating Arrays

NumPy provides multiple ways to create arrays depending on your needs. The most common method is using the np.array() function, but NumPy also includes built-in methods for creating:

✔ zeros
✔ ones
✔ sequences
✔ random values
✔ identity matrices
✔ custom ranges

🧩 1. Creating Array Using np.array()

Output:

Multi-Dimensional Array

⚙ 2. Creating Arrays with Built-In Functions

🔹 zeros(): Create array of zeros

Output:

2D zeros array:

🔹 ones(): Create array of ones

Output:

🔹 full(): Create array with a given value

Output:

🔢 3. Creating Number Sequences

🔹 Using arange() (like Python range)

Output:

🔹 Using linspace() (evenly spaced values)

Output:

🔁 4. Identity & Eye Matrices

🔹 identity()

Output:

🔹 eye() (identity with control over diagonal shift)

🎰 5. Random Arrays

Random integers:

📏 6. Creating Empty Array (Uninitialized memory)

⚠ Values are random (not zeros).
