3. Python’s import as Statement The import as statement helps the user provide an alias name to the original module name. # python import as import math as M print(M.pi) print(M.floor(3.18)) Output: 3.141592653589793 3 4. Importing user-defined modules We can import the functions of ...

例如,我们可以在另一个名为main.py的脚本中导入my_module模块,并使用其中的函数: frommy_packageimportmy_module my_module.my_function() 1. 2. 3. 在这个例子中,Python解释器会按照上述规则查找my_package包的所在路径。如果找到了该包,就会导入其中的my_module模块,并执行其中的my_function函数。 包的关系图...
