在线云评测系统日志（十）：获取输入文件的评测数据进行程序评测

获取评测数据的个数

def get_data_count(problem_id):
'''获得测试数据的个数信息'''
full_path = os.path.join(config.data_dir, str(problem_id))
try:
files = os.listdir(full_path)
except OSError as e:
logging.error(e)
return 0
count = 0
for item in files:
if item.endswith(".in") and item.startswith("data"):
count += 1
return count


运行程序，把结果输出到一个临时的输出文件中
