2.你可以使用-O或者-OO转换python命令来减少编译模块的大小 -O转换会帮你去掉assert语句 -OO转换会帮你去掉assert语句和__doc__文档字符串 由于一些程序可能依赖于assert语句或文档字符串,你应该在在确认需要 的情况下使用这些选项。 3.在速度上从.pyc文件中读指令来执行不会比从.py文件中读指令执行更快,只有在模块被加载时,.py
# test_hashtable.py def test_should_always_pass(): assert 2 + 2 == 22, "This is just a dummy test" Copied! The framework leverages the built-in assert statement to run your tests and report their results. That means you can just use regular Python syntax, without importing any sp...
assertEqual(len(pagination_requests), 1) If you run your test code at this point, you’ll get one failed and two passed tests. Navigate into your top-level books/ directory, if you’re not already there, then run the unittest command: Shell (venv) $ python -m unittest .F. ===...

assert else import pass break except in raise 这些单词都可以在我们的英语词典中找到。此外,如果我们在词典中搜索单词return,它只会给我们返回原始位置的动词含义。Python 中也使用相同的语义;当你在函数中使用 return 语句时,你是在从函数中取出一些东西。在接下来的章节中,我们将看到所有这些关键字的用法。
