 ...

 

• getcwd

Get the pathname of the Current Working Directory.

os.getcwd()
>>>
'/Users/joohyunyoon/workspace/sensor_fusion/nd013-c2-fusion-exercises'

 

• sys.path.append()

 If you add some specific path what you want to the list, you can import the .py file from the specific path.

sys.path.append(os.getcwd())

sys.path

['/Users/joohyunyoon/.pyenv/versions/anaconda3-2021.05/envs/sensor_fusion/lib/python37.zip'
