首先打开系统设置到环境变量的设置界面,找到PYTHONPATH的变量名,如果有就直接编辑,如果没有就新创建,创建的路径就写当前需要导入文件的文件夹路径 点击确定之后再在python.exe上直接import模块,此时可能还会提示no module name的错误,那么你就摊上大事儿了,说明你得把python重启一遍...
Modulesare Python.pyfiles that consist of Python code. Any Python file can be referenced as a module. A Python file calledhello.pyhas the module name ofhellothat can be imported into other Python files or used on the Python command line interpreter. You can learn about creating your own m...

1,import random 导入模块的所有方法 这会将对象(这里的对象指的是包、模块、类或者函数,下同)中的所有内容导入。如果该对象是个模块,那么调用对象内的类、函数或变量时,需要以module.xxx的方式。 2,import multiprocessing as mul 模块别名 3,from django.core import handlers 导入模块的单个方法 ...

PEP 328 – Imports: Multi-Line and Absolute/Relative 3. import 机制 日常编程中,为了能够复用写过的代码逻辑,我们都会把这些代码封装成为模块,需要用到的时候可以直接导入复用,以便提高我们的开发效率。module 能定义函数、类、变量,也能包含可执行的代码。module 来源有3种: ...
