Python3有一个注释功能。我应该用它代替文件字符串吗? I. e。什么是正确的方式:
def func(points: [{'x': int, 'y': int}]): -> int
pass
VS
def func(points):
''' Take a list of dicts, dict present a point, and contain keys:
'x' - int, x position
'y' - int, y position
Return int
'''
pass
答案 0 :(得分:0)
不,它们是文档字符串的补充。来自官方功能注释pep:
Because Python's 2.x series lacks a standard way of annotating a function's
parameters and return values, a variety of tools and libraries have appeared to
fill this gap.
但是Python社区喜欢标准化的东西(参考文献PEP
)。因此,他们提出了功能注释,主要针对第三方库和工具 - IDE,代码质量/静态分析工具等。正如PEP
所说:
By itself, Python does not attach any particular meaning or significance to
annotations.(...)meaning comes from third-party libraries alone.
