如何从python中的文本文件中删除NUL字节

Question

我的输出文件为每一行创建NUL字节（\ x00）。我在Unix上运行python 2.7，稍后将在Windows上处理文件

with open(inputfile,'w') as f:
           f.write(cmd_output)


command_process = subprocess.Popen(
cmd,
shell=shl,
stdin=subprocess.PIPE,
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT,
universal_newlines=True
)


 cmd_output = command_process.communicate()[0]
