A tuple is a container which holds a series of comma-separated values (items or elements) between parentheses. Tuples are immutable (i.e. you cannot change its content once created) and can hold mix data types. Creating Tuples To create an empty tuple or create a tuple with single elemen...
python 的data格式 python中的datatype,type函数利用type()函数可以查看数据的类型,比如说是str类型,在编辑器中写上str,按住ctrl,点击str,就到了源码定义的部分,所有str的功能都在这里了,同样,对于一个str变量temp,temp.upper(),按住ctrl,点击temp.upper()也跳到了
dataType输入参数的类型是DataType。 对于输入表参数,这是表示表列的StructType。 value作为Optional[Any]的输入参数的值。 对于非常数表参数或文本标量参数,这是None。 isTable输入参数是否是作为BooleanType的表。 isConstantExpression输入参数是否为常量可折叠表达式,并以BooleanType的形式呈现。

Slicing won’t be useful for this, as strings areimmutabledata types, in terms of Python, which means that they can’t be modified. What we can do is create a new string based on the old one: We’re not changing the underlying string that was assigned to it before. We’re assigning...
