PythonでPATHを取得する

Last updated at Posted at 2019-04-19

###前提
windows10
実行ファイル名:test.py
ディレクトリ構成:C:\Dev\hoge\test.py

###実行ファイル含めた絶対PATHを取得するとき

os.path.abspath(__file__)
>>> C:\Dev\hoge\test.py

###実行ファイルのディレクトリへの絶対PATHを取得するとき

import os
pwd = os.getcwd()
os.path.abspath(pwd)
>>> C:\Dev\hoge

もしくは

os.path.dirname(os.path.abspath("__file__"))
>>> C:\Dev\hoge

###dirname, basename, abspathについて
####os.path.dirname()

os.path.dirname(__file__)
>>> C:\Dev\hoge

os.path.dirname(__pwd__)
>>> C:\Dev

####os.path.basename()

os.path.basename(__file__)
>>> test.py

os.path.basename(__pwd__)
>>> hoge

####os.path.abspath()

os.path.basename(__file__)
>>> C:\Dev\hoge\test.py

os.path.basename(__pwd__)
>>> C:\Dev\hoge

###実行ファイル名を取得するとき
pathではないのですが、メモとして...

os.path.basename(__file__)
>>> test.py
a = __file__
print(a)
>>> test.py
