Why isn’t the sys.path in Spyder the same as in a shell?

In a shell python -c "import sys ; print(sys.path)" doesn’t give the same thing as if I stop the script at the first line with a breakpoint to do in the debugging console import sys ; print(sys.path).

I’ve managed to get around the issue by defining the necessary directories in Tools > PYTHONPATH Manager, but I find the method rather dirty as the sys.path is correct outside Spyder …
