当给logfile 参数指定了一个文件句柄时,所有从标准输入和标准输出获得的内容都会写入这个文件中(注意这个写入是 copy 方式的),如果指定了文件句柄,那么每次向程序发送指令(process.send)都会刷新这个文件(flush)。 这里有一个很重要的技巧:如果你想看到spawn过程中的输出,那么可以将这些输出写入到 sys.stdout 里去,比...

There is an option to tell PySimpleGUI to reroute all of your stdout and stderr output to this window. To do so call easy_print with the parameter do_not_reroute_stdout set to False. After calling it once with this parameter set to True, all future calls to a normal print will go ...
