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。
[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:
