Python numpy.ndarray.byteswap()用法及代碼示例

numpy.ndarray.byteswap()函數通過返回字節包裝的數組(可選地就地交換)在低端和大端數據表示之間切換。

用法： ndarray.byteswap(inplace=False)

代碼1：

# Python program explaining  
# byteswap() function  
import numpy as geek 
  
# a is an array of integers. 
a = geek.array([1, 256, 100], dtype = np.int16) 
   
print(a.byteswap(True))

輸出：

[256  1  25600]

代碼2： byteswap()函數不適用於字符串數組。

# Python program explaining  
# byteswap() function  
import numpy as geek 
  
# a is an array of strings 
a = geek.array(["arka","soumen","simran"],dtype = np.int16) 
  
print(a.byteswap(True))

輸出：

ValueError                                Traceback (most recent call last)
 in ()
      1 import numpy as geek
----> 2 a = geek.array(["arka","soumen","simran"],dtype = np.int16)
      3 
      4 #a is an array of strings
      5 

ValueError: invalid literal for int() with base 10: 'arka'
