我们可以在子类中使用super函数来访问父类的私有变量。 classParent:def__init__(self):self.__private_var=42defget_private_var(self):returnself.__private_varclassChild(Parent):defaccess_private_var(self):print(super().get_private_var())child=Child()child.access_private_var() 1. 2. 3. 4....
然后我们创建了一个子类Child，它继承了Parent类。在Child类中，我们定义了一个方法access_private_value(...
split()方法更常用于从路径中获取文件名: # Gather other propertiesprint("Is a symlink: ", os.path.islink(file_path))print("Absolute Path: ", os.path.abspath(file_path))print("File exists: ", os.path.exists(file_path))print("Parent directory: ", os.path.dirname(file_path))print("Par...

The somewhat cryptic output means that the first variable refers to the local first_child() function inside of parent(), while second points to second_child().You can now use first and second as if they’re regular functions, even though you can’t directly access the functions they point...

Python code in one module gains access to the code in another module by the process of importing it. 简单来说,我们日常看到的.py文件,都称作是一个module。 当你的 python 代码需要获取外部的一些功能(一些已经造好的轮子),你就需要使用到 import 这个声明关键字。import可以协助导入其他 module 。(类似...
The Context class has the following string attributes: Expand table AttributeDescription function_directory The directory in which the function is running. function_name The name of the function. invocation_id The ID of the current function invocation. thread_local_storage The thread local storage ...
This provides access to the Tcl interpreter. Each widget that is attached the same instance of Tk has the same value for its tk attribute. master The widget object that contains this widget. For Tk, the master is None because it is the main window. The terms master and parent are ...
