如何在命令提示符中将 \r\n 显示为实际的换行符？

Question

I have this Python code which goes like

output = str(check_output(["./listdevs.exe", "-p"]))
print (output)

When running this Python code in the Command Prompt, I'm met with this output

b'80ee:0021\r\n8086:1e31\r\n'

Instead of the above output, I would like to display it where the \r \n is replaced with an actual new line where it would look like

'80ee:0021
8086:1e31'

Answer 1

The result is in bytes. So you have to call decode method to convert the byte object to string object.

>>> print(output.decode("utf-8"))

Answer 2

If you are using Python 3.7+, you can pass text=True to subprocess.check_output to obtain the results as a string.

Prior to 3.7 you can use universal_newlines=True . text is just an alias for universal_newlines .

output = str(subprocess.check_output(["./listdevs.exe", "-p"], text=True))
