Python子进程的通用实践
不幸的是，我仅限于Python2.4，我希望在脚本执行时运行ascii动画（即旋转循环），我只是想知道这样做的常用方法或实践是什么，以及与解决方案相关的任何/所有资源，示例脚本将非常棒！！我一直在使用os.sytem（'command'），希望改掉这个习惯Python子进程的通用实践,python,python-2.4,Python,Python 2.4,不幸的是，我仅限于Python2.4，我希望在脚本执行时运行ascii动画（即旋转循环），我只是想知道这样做的常用方法或实践是什么，以及与解决方案相关的任何/所有资源，示例脚本将非常棒！！我一直在使用os.sytem（'command'），希望改掉这个习惯 谢谢 一种可能的方法是使用回车符“\r”将光标返回到行首，以便覆盖以前写入的字符。这允许您创建动画，只要它适合当前行。例如： import time def do_a_little_work(): time.sleep(0.1)
