How To Define Array In Python?

Use a list: `arr = [1, 2, 3]`

Use the `array` module: `from array import array`

Create a typed array: `arr = array(‘i’, [1, 2, 3])`

Use NumPy arrays: `import numpy as np`

Create a NumPy array: `arr = np.array([1, 2, 3])`

Create an empty list: `arr = []`

Create a fixed-size list: `arr = [0] * 5`

Create a list with mixed values: `arr = [1, “a”, 3.5]`
