返回更改 stem 的新路径。如果原始路径没有名称,则会引发 ValueError: >>> p = PureWindowsPath('c:/Downloads/draft.txt') >>> p.with_stem('final') PureWindowsPath('c:/Downloads/final.txt') >>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz') >>> p.with_stem('lib') PureWindows...
python 3.8没有with_stem方法需要至少升级到3.9或者改成i.with_name(f'村{a}{i.suffix}')
with_stem(stem) 该方法将路径中原本的stem替换为新的stem,如果路劲中本身不存在name,则抛出ValueError错误 In [51]: p1.with_stem('new') Out[51]: PurePosixPath('/Users/jeffery/new.txt') ## 用os.path实现 In [52]: from os.path import join, split, splitext In [53]: join(split("/Users/...

To the one with a hammer, everything looks like a nail. (手中有锤,看什么都像钉) 这句话是什么意思呢? 就是你不能只掌握数量很少的方法、工具。 否则你的认知会被自己能力框住。不只是存在盲点,而是存在“盲维”。 你会尝试用不合适的方法解决问题(还自诩“一招鲜,吃遍天”),却对原本合适的工具视...
