编写程序输入一WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.行字符

您可以使用以下代码来输出"WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead."这一行字符：

print("WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.")

这段代码会在控制台输出该行字符。请注意，这是一个警告信息，意味着在开发环境中使用该服务器时需要注意，并且建议在生产环境中使用WSGI服务器代替。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
