Copy
numpy.amin(a, axis=None, out=None, keepdims=False, initial=None, where=True)Parameters
| Parameter | Type | Description |
|---|---|---|
a | array_like | Input array from which the minimum value is computed. |
axis | None, int, or tuple of ints, optional | Axis or axes along which to find the minimum. If None, the minimum of the flattened array is returned. |
out | ndarray, optional | Alternative output array to store the result. Must have the same shape as expected output. |
keepdims | bool, optional | If True, the reduced dimensions are kept as size one, allowing proper broadcasting. |
initial | scalar, optional | Specifies an initial minimum value for empty arrays. |
where | array_like of bool, optional | Specifies elements to include in the comparison for the minimum value. |
Return Value
Returns a scalar or an array containing the minimum values. If axis=None, a scalar value is returned. If axis is specified, an array with the reduced dimension is returned.

import numpy as np
# Define an array
arr = np.array([3, 1, 4, 1, 5, 9, 2, 6])
# Find the minimum value
min_value = np.amin(arr)
# Print the result
print("Minimum value in the array:", min_value)Output:
Minimum value in the array: 1
