python - Python findall \n 与正则表达式

问题描述

试图让所有组

76630000 76746000 ucrtbase
76750000 76764000 profapi
...

从字符串loaded_modules_raw

'start end module name\n76630000 76746000 ucrtbase (deferred) \n76750000 76764000 profapi (deferred) \n76770000 76840000 KERNEL32 (deferred) \n76840000 768bc000 msvcp_win (deferred) \n768c0000 76903000 sechost (deferred) \n76920000 76af8000 KERNELBASE (deferred) \n77090000 770d5000 SHLWAPI (deferred) \n770e0000 776a7000 windows_storage (deferred) \n776b0000 776d2000 GDI32 (deferred) \n776e0000 77758000 ADVAPI32 (deferred) \n777c0000 7787d000 msvcrt (deferred) \n77880000 77896000 win32u (deferred) \n778a0000 77928000 shcore (deferred) \n77940000 77965000 IMM32 (延迟）\n779c0000 77b4c000 ntdll（pdb 符号）D:\NG\bin\Debug\wntdll.pdb\E04B114840C9B587E2E333AED97D8C9A1\wntdll.pdb\n\n卸载的模块：\n76910000 76916000 psapi.dll\n'

和

loaded_modules = re.findall(r"\\n(\w+)\s(\w+)\s+(\w+)",loaded_modules_raw)

试过了re.DOTALL

结果我得到None为什么？
