Linux下运行python脚本,pudb是一个不错的调试器。

语法高亮,断点,调用栈,命令行,都有了,如下图。

[笔记]Python的调试器pudb简易教程

[安装]

pip install pudb

[使用]

pudb xxx.py

[快捷键]

最常用的快捷键,应该是如下几个:

  • n - step over ("next") # 运行到下一行
  • s - step into # 运行进函数
  • c - continue # 继续运行
  • r/f - finish current function # 结束当前函数
  • b - toggle breakpoint # 打断点/取消断点
  • V - focus variables # 聚焦在变量窗口
  • f1/?/H - show this help screen # 显示帮助窗口
  • Ctrl-n/p - browse command line history # 浏览命令行历史
  • t/r/s/c - show type/repr/str/custom for this variable # 切换type/repr/str/custom

界面下按?就能出来快捷键列表,如下:
