os.path.idsir() return different result for absolute path and path created with os.path.join() metho-CodePudding

>>> os.getcwd()
'/Users/seungjunlee/test_dir'
>>> p1 = os.path.abspath('sub_1')
>>> p2 = os.path.join('test_dir', 'sub_1')
>>> os.path.isdir(p1)
True
>>> os.path.isdir(p2)
False

So the current working directory is test_dir, and there is sub directory called sub_1. p1 stores absolute path of sub_1 and p2 get path using join method of path module.

But thing is os.path.isdir(p1) and os.path.isdir(p2) yield different result. How is this possible, what U'm missing here?

CodePudding user response：

You are already under the directory of test_dir, and os.path.join('test_dir', 'sub_1') returns test_dir\\sub_1.

So, in fact what you are checking is /Users/seungjunlee/test_dir/test_dir/sub_1, surely it's not valid dir.
