常见的想当然
a pre-release like 2.1a1 is contained in the range >=2.0 because it evaluates as strictly greater than 2.0
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- SpecifierSet('>=2.0').contains('2.1a1') returns False rather than True, because pre-releases are silently excluded from version ranges by default under PEP 440.
- assert Version('2.1a1') > Version('2.0')
- assert not SpecifierSet('>=2.0').contains('2.1a1')
- assert SpecifierSet('>=2.0').contains('2.1a1', prereleases=True)
