您可以定义一个自定义函数以确保source是一个文件（使用os.path.isfile函数）：
8、os.mkdir(path, mode=0o777, *, dir_fd=None)Create a directory.If dir_fd is not None, it should be a file descriptor open to adirectory,and path should be relative; path will then be relative to that directory.dir_fd may not be implemented on your platform.If it is unavailable,...
symlink will be created instead of copying the file it points to. """ if _samefile(src, dst): raise SameFileError("{!r} and {!r} are the same file".format(src, dst)) for fn in [src, dst]: try: st = os.stat(fn) except OSError: # File most likely does not exist pass e...
Special cases aren't special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one—and preferably only one—obvious way to do it. ...
Finally, to start Electrum: $ ./run_electrum Run tests Run unit tests withpytest: $ pytest tests -v To run a single file, specify it directly like this: $ pytest tests/test_bitcoin.py -v Creating Binaries Linux (tarball) Linux (AppImage) ...
new_path = os.path.join('archive', file_name) shutil.move(file_name, new_path) 而且,由于不同的操作系统使用的分隔符不同,使用字符串拼接路径就容易出现问题。 有了pathlib,使得上述的问题变得更加轻松,pathlib创建的Path对象,可以直接通过正斜杠运算符/连接字符串生成新的对象。
# this is anotherline 在文件中写入行 若要将文本写入特殊的文件类型（例如JSON或csv），则应在文件对象顶部使用Python内置模块json或csv。import csv import json withopen("cities.csv", "w+") as file:writer = csv.DictWriter(file, fieldnames=["city", "country"])writer.writeheader()writer.writerow(...
