【问题描述】:
作为代码的一部分,我的功能如下:
def match_output(orig_path: Path,lines: Iterable[str],stem: str, delim: str,delim_pred: Callable[[int], bool],) -> Iterable:
n = 0
path = orig_path.with_stem(f'{orig_path.stem}_{stem}')
with path.open('w') as f:
for line in lines:
n_delim = line.count(delim)
matched = delim_pred(n_delim)
if matched:
f.write(line)
n += int(matched)
yield
logger.info(f'Number of {stem} lines: {n}')
但是,我遇到属性错误,无法解决,希望有什么建议吗?
Traceback (most recent call last):
File "C:/Users/HAXY8W/Desktop/pieter_code_rewriting/main.py", line 95, in <module>
main()
File "C:/Users/HAXY8W/Desktop/pieter_code_rewriting/main.py", line 88, in main
process(
File "C:/Users/HAXY8W/Desktop/pieter_code_rewriting/main.py", line 82, in process
for n_lines, _ in enumerate(zip(*iters)):
File "C:/Users/HAXY8W/Desktop/pieter_code_rewriting/main.py", line 27, in match_output
path = orig_path.with_stem(f'{orig_path.stem}_{stem}')
AttributeError: 'WindowsPath' object has no attribute 'with_stem'
我对 Pathlib 和 Stem 非常陌生,比我聪明的人建议我研究一下,如果这个问题听起来很新手,请道歉
【问题讨论】:
-
你的 Python 版本是多少?
with_stem最近才在 Python 3.9 中引入 -
是的,你是对的,版本问题。我的是 3.8... 你有旧版本的解决方案/替代品吗?
-
当然,我将其添加为答案

感谢您的帮助
