(tuple 是用多少申请多少) 除了上面人尽皆知的区别,还有一个区别:typing hint 现在写 python 代码如果还不加 typing hint 的话,就太过分了! 先说结论 如果元素的 type 都是一样的,就用 list 如果元素的 type 是不一样的,就用 tuple 举一个例子: defhandle(user_id:int) ->tuple[bool,str]:ifuser_id...
Note that in this class, you provide the named fields as class attributes with their corresponding type hint. In the case of the position field, you also provide a default value, "Python Developer". This default can be handy in many situations. Now you’re ready to load the data from ...
print("值:%r,类型:%r" % (tup, type(tup))) #值:(1, 2, 3, 4, 5),类型:<class 'tuple'> 续行操作 在Python中,元组中的数据项如果过多,可能会导致整个元组太长,太长的元组是不符合PEP8规范的。 每行最大的字符数不可超过79,文档字符或者注释每行不可超过72 Python虽然提供了续行符\,但是在...
比较出人意料的是，Python 在 type hint 中也是支持variadic generics的。你可以写出如下代码 T=TypeVar...
Another immutable data type in Python is thetuple. At times, it's useful create a data structure that won't be altered later in a program. That structure might protect constant data from being overwritten by accident or improve performance for iterating over data. These situations are where ...

Python虽然提供了续行符\,但是在元组中可以忽略续行符,如下所示: code tup = ( 1, 2, 3, 4, 5 ) print("值:%r,类型:%r" % (tup, type(tup))) #值:(1, 2, 3, 4, 5),类型:<class 'tuple'> 类型转换 元组支持与布尔型、字符串、列表、以及集合类型进行类型转换: ...
