3.2 绝对导入(Absolute Import)与相对导入(Relative Import) Python 有两种 import 方法,绝对导入及相对导入。 3.2.1 绝对导入 绝对导入基于当前运行脚本所在目录和sys.path列表中的路径进行搜索。具体步骤参考第 3.1.2 节。 此时sys.path列表中保存有 Pythonx.x 标准库的路径(xxx/lib等等)。绝对导入的用法举例如下...
If you’ve worked on a Python project that has more than one file, chances are you’ve had to use an import statement before. In this tutorial, you’ll not only cover the pros and cons of absolute and relative imports but also learn about the best practi
import应该根据用途分为以下三类: 标准库导入(Python的内置模块) 相关的第三方导入(已安装但不属于当前应用程序的模块) 本地应用程序导入(属于当前应用程序的模块) 每个import都要用空格分隔 在每个导入组中按字母顺序排列导入也是一个好主意。这使得查找特定导入变得更加容易,特别是当一个文件中有许多导入时。以下是...
首先,运行主程序python main.py,一切正常。再以脚本的形式运行模块python spider/realtime/overview.py,报错:ImportError: attempted relative import with no known parent package。 经过一番搜索,查阅了一些文章,终于搞明白,原来在 Python 中,相对导入的实现,是极度依赖__name__内置变量的。当模块以import导入的方式...
Python代码中,既可以导入模块,也可以导入模块中的对象,导入方式主要分为两种:import <module_name>和from <module_name> import <name(s)>。本文主要对二者进行比较。为了之后测试,定义了一个module模块,module.py文件定义如下: 代码语言:javascript 代码运行次数:0 ...
