我正在尝试创建86个task.py实例以同时运行。
import sys import subprocess for file in range(86): subprocess.call([sys.executable,'task.py',str(file)+'in.csv',str(filen)+'out.csv'])
subprocess.call等待命令完成。subprocess.Popen改为使用:
subprocess.call
subprocess.Popen
import sys import subprocess procs = [] for i in range(86): proc = subprocess.Popen([sys.executable, 'task.py', '{}in.csv'.format(i), '{}out.csv'.format(i)]) procs.append(proc) for proc in procs: proc.wait()
