Working Directory

Get a path to the current Python file

curr_file = pathlib.Path(__file__)
print(curr_file)

 

 

Get a path to the current working directory

cwd = pathlib.Path.cwd()
print(cwd)

 

Get a first parent folder path

parent folder 찾기 

one_above = pathlib.Path.cwd().parent 
print(one_above)

 

Get an Nth parent folder path

N번째 상위 폴더를 찾는 방법

mul_above = pathlib.Path.cwd().parent.parent.parent

mul_above = pathlib.Path.cwd().parents[1]
print(mul_above)

Join paths

Create a directory if it doesn’t exist

tgt_path = pathlib.Path.cwd().joinpath('reports')

if not tgt_path.exists():
    tgt_path.mkdir()

 

Create files

reports라는 폴더에 파일 생성하기 

tgt_path = pathlib.Path.cwd().joinpath('reports')

tgt_path.joinpath('summer-sales.csv').touch(exist_ok=True)
tgt_path.joinpath('winter-sales.txt').touch(exist_ok=True)

Check if the path is a folder

폴더가 있는 지 여부 확인

tgt_path = pathlib.Path.cwd().joinpath('reports')

print(tgt_path.is_dir())
print(tgt_path.joinpath('summer-sales.csv').is_dir())

Check if the path is a file

 

tgt_path = pathlib.Path.cwd().joinpath('reports')

print(tgt_path.is_dir())
print(tgt_path.joinpath('summer-sales.csv').is_file())

 

Get the name of the file

tgt_path = pathlib.Path.cwd().joinpath('reports/summer-sales.csv')
print(tgt_path.name)

Get the file extension

tgt_path = pathlib.Path.cwd().joinpath('reports/summer-sales.csv')
print(tgt_path.suffix)
#.csv

Iterate over files in a folder

tgt_path = pathlib.Path.cwd().joinpath('reports')

for file in tgt_path.iterdir():
    print(file)
