numpy.ndarray.flatten numpy.ndarray.flat numpy.ravel 此函数返回折叠为一维的数组的副本。该函数采用以下参数。 ndarray.flatten(order) 这里 序号 参数和描述 1 order 'C' 行主要(默认。'F':列主要'A':以列主要顺序展平,如果a是Fortran在内存中连续,则行主要顺序否则'K':按顺序压扁a发生在记忆中 例 import numpy as np a = np.arange(8).reshape(2,4) print 'The original array is:' print a print '\n' # default is column-major print 'The flattened array is:' print a.flatten() print '\n' print 'The flattened array in F-style ordering:' print a.flatten(order = 'F') 上述方案的输出如下 The original array is: [[0 1 2 3] [4 5 6 7]] The flattened array is: [0 1 2 3 4 5 6 7] The flattened array in F-style ordering: [0 4 1 5 2 6 3 7] numpy.ndarray.flat numpy.ravel
