For the use of python Interactive window for , You can add a path to add a path to the python In recognizable path . The following code is used ：
import sys
sys.path.append(' Paths to be added ')
You can then import “ Paths to be added " Medium python modular .
For paths that need to be added , stay windows In the system , The separator agrees to use double backslashes \\ express , as ：C:\\Users\\Administrator\\source\\repos\\python-sklearn-regression-cookiecutter
It is particularly important to note that , except c: It's coming next \\ If you use \ replace , The system will prompt an error , If you use double slashes in other locations \ replace , So it's in execution sys.path.append(' Paths to be added ') Sentence time , No mistake , But it may not get a valid path , This leads to subsequent errors . such as ：
sys.path.append('C:\\Users\Administrator\source\repos\python-sklearn-regression-cookiecutter')
After implementation , input sys.path The specific path is shown as ：
【'C:\\Users\\Administrator\\source\
repos\\python-sklearn-regression-cookiecutter'】
Note that the red one is a single diagonal line , Instead of a double slash
, The other positions are automatically replaced by double oblique lines （ I don't know why ???）, only source This one in the back \ Not replaced , It seems to be \r Caused by an escape symbol . And this path is not correct , The corresponding module in the path cannot be imported later .
therefore , Remember , When writing the path in the interactive window , Use both \\ To separate , Don't use it \ To separate .
