修改 sys.path

Question

PYTHON 3.3 I have my HDD partitioned with programmes on "C" and data on "D" one NTFS and the other fat32. I've downloaded examples of code from one of the popular manuals onto "D". Running sys.path does not show these. I've looked, but cannot find the sys.path file to permanently add my "path". I can have the sys.path come up in IDLE, but making changes here are only temporary I believe. It is a small irritation to have to "go looking" each time. I'd really appreciate some comments, and apologize if this has already been answered somewhere else.

Answer 1

您可以修改环境变量PYTHONPATH来调整 Python 在导入时查找模块的默认路径。

Answer 2

For instance, to add the directory /home/me/mypy to the path, just do:

import sys

sys.path.append("/home/me/mypy")
