Python

Last updated at 2017-01-11Posted at 2014-05-25

引数に絶対パスがあると、その前の引数は無視されるので注意。

(ref. https://docs.python.org/3.3/library/os.path.html#os.path.join)

os.path.join

>>> os.path.join('/test', '/hoge', '/piyo')
'/piyo'

>>> os.path.join('/test', 'hoge', '/piyo')
'/piyo'

>>> os.path.join('/test', 'hoge', 'piyo')
'/test/hoge/piyo'
