brainpy.math.random.shuffle#
- brainpy.math.random.shuffle(x, axis=0, key=None)[source]#
Modify a sequence in-place by shuffling its contents.
This function only shuffles the array along the first axis of a multi-dimensional array. The order of sub-arrays is changed but their contents remains the same.
- Parameters:
x (ndarray or MutableSequence) – The array, list or mutable sequence to be shuffled.
- Return type:
None

Examples
>>> arr = np.arange(10) >>> brainpy.math.random.shuffle(arr) >>> arr [1 7 5 2 9 4 3 6 0 8] # random
Multi-dimensional arrays are only shuffled along the first axis:
>>> arr = np.arange(9).reshape((3, 3)) >>> brainpy.math.random.shuffle(arr) >>> arr array([[3, 4, 5], # random [6, 7, 8], [0, 1, 2]])
