Python3实现 # subscript print(u'Hu2082SOu2084')# H?SO? # superscript print("xu00b2 + yu00b2 = 2")# x2 + y2 = 2 输出: H?SO? x2+y2=2 注:本文由VeryToolz翻译自How to print Superscript and Subscript in Python?,非经特殊声明,文中代码和图片版权归原作者muazzamfaraaz所有,本译文的传播和使用请遵循“署名-相同方式共享 4.0 国际 (CC BY-SA 4.0)”...
which doesn't support this operation. The key to fixing and preventing it lies in maintainingtype consistency. Always ensure that variables you intend to subscript actually hold a subscriptable type (like a list, tuple, or string) at the
We printed a number in the subscript notation to the console in the first line. We just specified the Unicode namesubscript twoin the\N{}escape sequence. This Unicode name is case-insensitive, which means we can use either uppercase or lowercase Unicode names. ...
像 PyWrapperDescr_Type 的 tp_descr_get 设置了 wrapperdescr_get,故称 PyWrapperDescrObject 为 descriptor。 如上图来说,实际上 mp_subscript 和 d_wrapped 都是函数指针变量,它们的值相等,都是 list_subscript 。 如下的例子重写了list 的 '__repr__ ' 方法,则初始化完成后的 A 如下图所示: class A...
>>> # Dot notation >>> CardinalDirection.NORTH <CardinalDirection.NORTH: 'N'> >>> # Call notation >>> CardinalDirection("N") <CardinalDirection.NORTH: 'N'> >>> # Subscript notation >>> CardinalDirection["NORTH"] <CardinalDirection.NORTH: 'N'> 本例中突出显示的第一行显示了如何使用...
If you provide a scalar argument for the name, that argument will be transformed to have a subscript that corresponds to the index of the associated variable. For example, if you do x = model.addVars(2,3,name="x"), the variables will get names x[0,0], x[0,1], etc. Parameters:...
You can subscript a dictionary using specific keys to get their associated values. Key lookup in dictionaries is quite an efficient operation because dictionaries are implemented as hash tables.If you refer to a key that isn’t in the dictionary, then Python raises an exception:...
Concrete pointer types are created by calling POINTER() with the type that will be pointed to; this is done automatically by pointer(). If a pointer points to an array, its elements can be read and written using standard subscript and slice accesses. Pointer objects have no size, so len(...
target is a single node and can be a Name, a Attribute or a Subscript. annotation is the annotation, such as a Constant or Name node. value is a single optional node. simple is a boolean integer set to True for a Name node in target that do not appear in between parenthesis and ...
