pandas 3.7中的pathlib联合路径

from pathlib import Path

path1 = Path('/path/to')
path2 = Path('file.txt')

new_path = path1.joinpath(path2)
print(new_path)  # 输出: /path/to/file.txt

from pathlib import Path

path = Path('/path/to/file.txt')

parent_dir = path.parent
print(parent_dir)  # 输出: /path/to

from pathlib import Path

path = Path('/path/to/file.txt')

file_name = path.name
print(file_name)  # 输出: file.txt

from pathlib import Path

path = Path('/path/to/file.txt')

file_suffix = path.suffix
print(file_suffix)  # 输出: .txt

from pathlib import Path

path = Path('/path/to/file.txt')

if path.exists():
    print('路径存在')
else:
    print('路径不存在')
