python將內存視圖轉換為字符串

Question

我試圖到處搜索，但找不到任何相關信息。

以下代碼的結果：

overlapped = pywintypes.OVERLAPPED()
buffer = win32file.AllocateReadBuffer(1024*4)
fullDataRead = []
hr, data = win32file.ReadFile(handle, buffer, overlapped)
n = win32file.GetOverlappedResult(handle, overlapped, 1)
read = str(data[:n])
fullDataRead.append(read)
print(fullDataRead)

我得到

['<memory at 0x0000026821801348>']

但我需要里面的字符串或字節。 任何想法如何讀取memoryview對象？ 謝謝

Answer 1

可以使用.tobytes()將memory對象轉換為字符串，如下所示：

a = memoryview(b'mystring')
print(a)  # <memory at 0x10cbebb98>
print(a.tobytes())  # 'mystring'

Answer 2

對於 Python 2.7 和 3.x，你可以試試這個：

a = memoryview(b'mystring')
print(a)  # <memory at 0x10cbebb98>
#for string
print(str(a,'utf8'))  # 'mystring' as UTF-8

# for bytes
print(bytes(a))  # b'mystring'
