我创建一个这样的覆盖率报告：
nosetests --with-coverage --cover-html
我的.coveragerc文件如下所示：
# .coveragerc to control coverage.py
[run]
branch = True
omit = contextlib, ctypes, ctypes._endian, ctypes.util, filecmp, getpass, sets, subprocess, uuid
[report]
exclude_lines =
pragma: no cover
但我的报告看起来像这样：
..........

如何从报告中删除覆盖率为 0% 的标准库包？显然，将它们列出来omit并不像我期望的那样工作......
