sys.stdoutis a file object corresponding to the program's standard output. You can use its write()method. Note that it's probably not necessary to use the withstatement, because stdoutdoes not have to be opened or closed.
sys.stdout是对应于程序标准输出的文件对象。你可以使用它的write()方法。请注意，可能没有必要使用该with语句，因为stdout不必打开或关闭。
So, if you need to create a csv.writerobject, you can just say:
所以，如果你需要创建一个csv.writer对象，你可以说：
import sys
spamwriter = csv.writer(sys.stdout)
