How do i change directory to the directory with my python script in? So far I figured out I should use os.chdir and sys.argv[0]. I'm sure there is a better way then to write my own function to parse argv[0].
回答1:
os.chdir(os.path.dirname(__file__))
回答2:
os.chdir(os.path.dirname(os.path.abspath(__file__))) should do it.
os.chdir(os.path.dirname(__file__)) would not work if the script is run from the directory in which it is present.
回答3:
Sometimes __file__ is not defined, in this case you can try sys.path[0]
回答4:
on windows OS, if you call something like python somefile.py this os.chdir(os.path.dirname(__file__)) will throw a WindowsError. But this should work for all cases:
import os
absFilePath = os.path.abspath(__file__)
os.chdir( os.path.dirname(absFilePath) )
