在python脚本中设置环境变量

重击：

LD_LIBRARY_PATH=my_pathsqsub -np  /path/to/executable

在Python中类似：

import osimport subprocessimport sysos.environ['LD_LIBRARY_PATH'] = "my_path" # visible in this process + all childrensubprocess.check_call(['sqsub', '-np', sys.argv[1], '/path/to/executable'],env=dict(os.environ, SQSUB_VAR="visible in this subprocess"))
