Python 同步电脑上的文件夹路径

Python folder paths on synched pcs

我在两台不同的电脑上使用 .py 文件并使用 google 驱动器同步文件。 由于我经常使用子文件夹处理文件,因此我使用完整路径来读取 csv

passport = pd.read_csv(r'C:\Users\turbo\Google Drive\Studium\Master_thesis\Python\Databases\passport_uzb.csv')

但是,切换电脑时我必须手动更改路径,因为我的第二台电脑是:

C:\Users\turbo\My Drive\Studium\Master_thesis\Python\Databases

所以唯一的区别是 'Google Drive' =/= 'My Drive'

是否可以使用完整的文件路径来读取文件?

您可以使用 relative 路径而不是 absolute 路径来访问 CSV。 pathlib module is useful for this. For example, assuming your script is directly inside the ...Python/Databases folder, you can compute the path to the CSV like so, using the __file__ 模块属性:

from pathlib import Path

# this is a path object that always refers to the script in which it is defined
this_file = Path(__file__).resolve()

# this path refers to .../Python/Databases, no matter where it is located
this_folder = this_file.parent

csv_path = this_folder / "passport_uzb.csv"

passport = pd.read_csv(csv_path)

Edit:无论您的脚本位于何处,您都可以使用 .parent/ "child" 的某种组合来构造一个有效的相对路径.如果您的脚本在 ...Python/Databases/nasapower 中,则只需添加另一个 .parent:

this_file = Path(__file__).resolve()
nasapower_folder = this_file.parent
databases_folder = nasapower_folder.parent

或者您可以使用 .parents 序列来更快地到达那里:

databases_folder = Path(__file__).resolve().parents[1]

同样,对于输出文件夹:

output_folder = Path(__file__).resolve().parent / "json"
