以csv格式打印到stdout。在
这会下载一份更新的回顾表事件文件， 用7个CPU解析它们
^{pr2}$这使用了一个预先下载的retrosheet事件文件副本， 有7个CPU
$ time pycwevent -n 7 --data-root /tmp/retrosheet-master/event/regular/ > /tmp/events2.csv stderr: found 2254 files Warning: Invalid integer value 'b' real 1m57.499s user 9m52.236s sys 0m17.672s $ wc -l /tmp/events2.csv 13976184 /tmp/events2.csv
