from . import python3
The import system¶. Python code in one module gains access to the code in another module by the process of importing it. The import statement is the most common way of invoking the import machinery, but it is not the only way. Functions such as importlib.,Such a file is called a module; definitions from a module can be imported into other modules or into the main module (the collection of variables that you have access to in a script executed at the top level and in calculator mode). A module is a file con,Such a file is called a module; definitions from a module can be imported into other modules or into the main module (the collection of variables that you have access to in a script executed at the top level and in calculator mode). A module is a file con, A module is a file containing Python definitions and statements. The file name is the module name with the suffix .py appended. Within a module, the module's name (as a string) is available as the value of the global variable __name__. For instance, , 現在你在同一個目錄裡下有另一個module sample_module_import.py 想要重複使用這個function，這時可以直接從 sample_module import 拿取： from sample_module import sample_func if __name__ == '__main__': sample_func(). 跑 python3 sample_module_import.py 會得到： Hello! 再來是package。我們把 ..., Python 3 no longer supports that since it's not explicit whether you want the 'relative' or 'absolute' base .
