cron执行python无果

Question

执行以下crontab，xxx.py文件中有print输出：1816*/usr/local/python3/bin/python3.7/root/xxx.py1.确认了cron正常运行，测试了定时输出2.确认了/usr/local/python3/bin/python3.7/root/xxx.py可以执行，也得到了正确的结果3.确认了/var/log/cron有内容，看到了执行这个定时任务，记录如下：Nov2316:01:02localhostrun-parts(/etc/cron.hourly)[17754]:finished0yum-hourly.cronNov2316:10:01localhostCROND[17949]:(root)CMD(/usr/lib64/sa/sa111)Nov2316:17:04localhostcrontab[18958]:(root)BEGINEDIT(root)Nov2316:17:36localhostcrontab[18958]:(root)REPLACE(root)Nov2316:17:36localhostcrontab[18958]:(root)ENDEDIT(root)Nov2316:18:01localhostcrond[1076]:(root)RELOAD(/var/spool/cron/root)Nov2316:18:01localhostCROND[19014]:(root)CMD(/usr/local/python3/bin/python3.7/root/xxx.py)Nov2316:20:01localhostCROND[19630]:(root)CMD(/usr/lib64/sa/sa111)Nov2316:21:31localhostcrontab[19849]:(root)BEGINEDIT(root)Nov2316:23:50localhostcrontab[19849]:(root)ENDEDIT(root)4.确认了/usr/local/python3/bin/python3.7/root/xxx.py>>x.log可以执行，也加了2>&1,x.log都有正常的程序输出记录抓狂了，感觉都检查了都没问题，命令都用了绝对路径，就是没执行结果，中间执行输出记录也没有，貌似就没执行
