Python NumPy flatten方法用法及代码示例 Numpy 的flatten(~)方法返回输入数组的新扁平化版本。 如果您想避免创建新数组,请改用ravel(~)方法。 参数 由于很少使用order参数,因此此处省略该参数。 返回值 与a类型相同的一维 Numpy 数组。 例子 考虑以下二维数组: a = np.array([[3,4],[5,6]]) a array([[...
We learned different methods to make a flatten list from a list of lists in Python. We covered using nested for loops, list comprehension, reduce(), chain(), sum(), recursive solution, numpy’s flatten() method, and pandas’ stack() method. Leave a comment if you have any questions. ...
