if options.verbose:verbose_mode = True else:verbose_mode = False 这段代码中，`optparse`模块自动处理了`-v`或`--verbose`选项的输入，根据用户选择自动设置`verbose`标志。如果用户输入了该选项，`verbose_mode`变量将被设置为`True`，表示开启verbose模式；否则，`verbose_mode`保持为`False`，表...
1.8.1 控制异常: %xmode 大多数时候,当一个Python脚本未执行通过时,会抛出一个异常。当解释器捕获到这些异常时,可以在轨迹追溯(traceback)中找到引起这个错误的原因。利用%xmode魔法函数,IPython允许你在异常发生时控制打印信息的数量。 %xmode有一个输入参数,即模式。模式有3个可选项:Plain,Context和Verbose。默认情...

从中我们能看到Python解释器对应的可执行文件为python_d.exe,继续往下走可以看到代码进入case ‘v’,这里打开了verbose模式,这样Python解释器执行时会把很多信息打印出来。接下来在main.c中的pymain_run_command函数中设置断点,这个函数会调用一系列函数执行源码,该文件在Module目录下, ...
If any tests fail, you can re-run the failing test(s) in verbose mode. For example, iftest_osandtest_gdbfailed, you can run: make test TESTOPTS="-v test_os test_gdb" If the failure persists and appears to be a problem with Python rather than your environment, you canfile a bug...
