no_value = None # NoneType1.1.2 复合数据类型 复合数据类型则能够组合多个值形成更复杂的数据结构。主要包括列表(list)、元组(tuple)、字典(dict)和集合(set): •列表:有序且可变的元素序列,例如students = ["Alice", "Bob", "Charlie"]。 •元组:有序但不可变的元素序列,例如coordinates = (40.7128,...
python基础教程:dict(字典) 字典(dict, dictionary的简写)是Python中另一个非常重要的内置数据类型,是Python中映射类型(Mapping Type),它把“键”(key)映射到“值”(value),通过key可以快速找到value,它是一种“键值对”(key-value)数据结构。 “键”,可以是任意不可变的类型对象(可以做hash,即具有hash()和eq(...
--configure-<name><value>Optional. Sets a debug property that must be known to the debug server before the client connects. Such properties can be used directly inlaunchconfiguration, but must be set in this manner forattachconfigurations. For example, if you don't want the debug server to...
If there's only one output, we recommend using the return value. For multiple outputs, you'll have to use output parameters. To produce multiple outputs, use the set() method provided by the azure.functions.Out interface to assign a value to the binding. For example, the following ...
