在这个示例中,我们定义了一个main函数来执行整个流程:读取JSON文件、打印原始数据、修改指定key的值、打印修改后的数据,并将修改后的数据写回文件。你可以根据需要调整file_path、key_to_modify和new_value变量的值来适应你的具体场景。
# 定义主函数来执行以上步骤defmain():file_path='data.json'# 定义JSON文件路径data=read_json_file(file_path)# 读取JSON文件print("原始数据:",data)# 打印原始数据key_to_modify='name'# 假设我们需要修改的key是'name'new_value='John Doe'# 新的值modify_value(data,key_to_modify,new_value)# 修...

The Python Debugger extension then creates and opens alaunch.jsonfile that contains a pre-defined configuration based on what you previously selected, in this case,Python File. You can modify configurations (to add arguments, for example), and also add custom configurations. ...
You could also modify the decorator to return a pint Quantity directly. Such a Quantity is made by multiplying a value with the unit. In pint, units must be looked up in a UnitRegistry. You can store the registry as a function attribute on the decorator to avoid cluttering the namespace...
