我是靠谱客的博主阳光芒果，这篇文章主要介绍对话框之messagebox，现在分享给大家，希望可以做个参考。

messagebox消息框：

默认情况下，调用 messagebox 的工具函数时只要设置标题和提示区即可，提示区图标、按钮区的按钮都有默认设置；

messagebox函数9个：showinfo、showwarning、showerror、askquestion、askyesno、askyesnocancel、askokcancel、askretrycancel、messagebox._show(title、message、icon、type)

icon选项：“error”、“info”、“question”、“warning”

按钮类型type：“yesno”（是、否）、yesnocancel”（是、否、取消）、“ok”（确定）、“okcancel”（确定、取消）、“retrycancel”（重试、取消）、“abortretryignore”（取消、重试、忽略）
