如何使用子进程指定文件位置?
How can I specify file locations using subprocess?
我正在对 运行 多个 python 脚本使用子进程:
import subprocess
subprocess.run("python3 script1.py & python3 script2.py", shell=True)
如何指定脚本文件位置?
试试这个:
# main.py
import subprocess
subprocess.run(
"python3 script1.py & python3 script2.py",
cwd='my_dir',
shell=True,
)
$ tree .
.
├── main.py
└── my_dir
├── script1.py
└── script2.py
1 directory, 3 files
$cat my_dir/script1.py
print('script1')
$cat my_dir/script2.py
print('script2')
对于更复杂的情况:
from pathlib import Path
BASE_DIR = Path(__file__).parent
import subprocess
subprocess.run(
"python3 script1.py & python3 script2.py",
cwd=BASE_DIR / 'my_dir',
shell=True,
)
