Numpy ndarray.flatten()函数| Python

numpy.ndarray.flatten()函数返回折叠成一维的数组的副本。

Syntax : numpy.ndarray.flatten(order=’C’)

Parameters :
order : [{‘C’, ‘F’, ‘A’, ‘K’}, optional] ‘C’ means to flatten in row-major (C-style) order. ‘F’ means to flatten in column-major (Fortran- style) order. ‘A’ means to flatten in column-major order if a is Fortran contiguous in memory, row-major order otherwise. ‘K’ means to flatten a in the order the elements occur in memory. The default is ‘C’.

Return : [ndarray] A copy of the input array, flattened to one dimension.

# Python program explaining
# numpy.ndarray.flatten() function
  
# importing numpy as geek 
import numpy as geek
  
arr = geek.array([[5, 6], [7, 8]])
  
gfg = arr.flatten()
  
print( gfg )

输出 ：

[5 6 7 8]
