DISCORD // 'unicodeescape' 编解码器无法解码位置 2-3 中的字节：截断的 \\UXXXXXXXX 转义

Question

I'm trying to open discord with this script

import subprocess

subprocess.call(['C:\Users\xerxe\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Discord Inc\\Discord.exe'])

but only get this this error

'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

Answer 1

The \\ character is an escape character - \\n means a newline character, \\t is a tab character, etc. \\U is used to denote the beginning of a Unicode escape sequence, like \\U000145d3 , where the 8 chars following \\U are hex digits ( 0-9a-f ). Since \\Users\\xer is not a valid Unicode escape sequence, you got an error. For Windows paths, you either need to escape the escape character:

subprocess.call(['C:\\Users\\xerxe\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Discord Inc\\Discord.exe'])

use a raw string literal (note the r just before the opening ' ):

subprocess.call([r'C:\Users\xerxe\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Discord Inc\Discord.exe'])

or use / characters as path delimiters:

subprocess.call(['C:/Users/xerxe/AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Discord Inc/Discord.exe'])
