#启动Python的调试器pdb，让程序以单步方式运行，可以随时查看运行状态。我们先准备好程序：
#python -m pdb 2.3.pdb.py
s= '0'

print(10/n)
#以参数-m pdb启动后，pdb定位到下一步要执行的代码-> s = '0'。输入命令l来查看代码：
#输入命令n可以单步执行代码：
#任何时候都可以输入命令p 变量名来查看变量：
#输入命令q结束调试，退出程序：
#pdb.set_trace()
#这个方法也是用pdb，但是不需要单步执行，我们只需要import pdb，
# 然后，在可能出错的地方放一个pdb.set_trace()，就可以设置一个断点：
