python—将自定义函数的路径添加到系统路径中

1. 程序所在的文件路径

2. 标准库的安装路径

3. 操作系统环境变量PYTHONPATH所包含的路径

# 添加系统路径
import sys
sys.path.append(r"D:/PycharmProjects/Work preparation/九、人工智能项目班/scoredcard1/")
# 打印路径
print(sys.path)
from hello_word import helloworld

print(helloworld())

helloworld文件

def helloworld():
    return 'helloworld'

程序运行结果为

['D:\\PycharmProjects\\Work preparation\\九、人工智能项目班\\金融评分卡', 'D:\\PycharmProjects\\Work preparation', 'D:\\softwares\\JetBrains\\PyCharm 2020.1.2\\plugins\\python\\helpers\\pycharm_display', 'D:\\softwares\\anaconda3\\envs\\tf-gpu\\python36.zip', 'D:\\softwares\\anaconda3\\envs\\tf-gpu\\DLLs', 'D:\\softwares\\anaconda3\\envs\\tf-gpu\\lib', 'D:\\softwares\\anaconda3\\envs\\tf-gpu', 'D:\\softwares\\anaconda3\\envs\\tf-gpu\\lib\\site-packages', 'D:\\softwares\\JetBrains\\PyCharm 2020.1.2\\plugins\\python\\helpers\\pycharm_matplotlib_backend', 'D:/PycharmProjects/Work preparation/九、人工智能项目班/scoredcard1/']
