Predictable behaviours that make a human overhand shuffle imperfect. It would be pretty simple to implement your own using random. Python's NumPy package offers various methods that are used to perform operations involving randomness, such as the methods to randomly select one or more numbers from a given list of numbers, or to generate a random number in a given range, or to randomly generate a sample from a given distribution.. All these methods are offered under the random module of the NumPy package. The random.shuffle() function. This function only shuffles the array along the first axis of a multi-dimensional array. Drawback of this is that list ordering is lost in this process. 多谢各位. The key differences between the permutation () and shuffle () functions are that if passed an array, the permutation () function returns a shuffled copy of the original array. random.shuffle (x) # Shuffle-Funktion Python liest alle Dateien in der Datensatzdatei und mischt die Abteilung, um Trainingstest-TXT-Dateien zu generieren (generieren Sie train.txt, test.txt, die Reihenfolge ist zufällig, das Standardverhältnis ist 8: 2).
