importsys sys.path.append('/path/to/') 1. 2. 在PYTHONPATH环境变量中添加自定义函数文件所在的目录。将目录路径添加到PYTHONPATH环境变量后,Python解释器会将其作为搜索路径的一部分。 导入自定义函数:一旦添加了自定义函数文件的路径,我们就可以使用import语句将自定义函数导入到当前脚本中。导入后,我们就可以使...

Python Import Function - Learn how to use the import function in Python to include modules and libraries in your projects effectively.
import time def bar(): time.sleep(3) print('in the bar') def test(func): start_time = time.time() func() end_time = time.time() print('the func run time is%s'%(end_time-start_time)) test(bar) 1. 2. 3. 4. 5.
ns.myFunction() 这时,我们就有了两个不同的作用域:一个是 importingScript 的,一个是 nameScript 的。从图中就能看出和之前的区别: 在importingScript.py 里,__name__变量就被设置为"__main__"。当 import 导入 nameScript 的时候,Python 就在当前脚本运行目录和环境变量sys.path保存的路径中寻找对应名称的...

Module().test()File"module.py",line5,intest animal.run() AttributeError:'module' object has noattribute'run' 这是因为,在import animal 的时候,python 会创建一个对 模块名 animal 的引用,如果要访问该模块内其他方法或类时,需要写全,如 animal.attribute。
