In NumPy, you can create a 5x5 array with random values using numpy.random.rand. To sort each row of this array, use the numpy.sort function along the appropriate axis. By setting the axis parameter to 1, the function will sort the elements within each row independently, resulting in a ...
A custom key function can be supplied to customize the sort order, and the reverse flag can be set to request the result in descending order. >>> 2.参数说明 iterable 可迭代对象,如:str、list、tuple、dict都是可迭代对象(这里就不局限于list了) key 用列表元素的某个属性或函数进行作为关键字(此...
