Creating Tuples in PythonSimilar to lists, you’ll often create new tuples using literals. Here’s a short example showing a tuple definition:Python >>> connection = ("localhost", "8080", 3, "database.db") >>> connection ('localhost', '8080', 3, 'database.db') In this example...
Definition of Python 3 Tuple Python 3 tuple lists Python objects that can’t be changed. Like lists, tuples are made up of sequences. The most significant distinction between tuples and lists is that tuples, unlike lists, cannot be modified. Parentheses are used in tuples, but square brac...

(You will see a Python data type that is not ordered in the next tutorial on dictionaries.)Lists that have the same elements in a different order are not the same:>>> a = ['foo', 'bar', 'baz', 'qux'] >>> b = ['baz', 'qux', 'bar', 'foo'] >>> a == b False>>> ...

In this example, you update Joe’s name by assigning a new value to its .name attribute. If you’d like to avoid this behavior, then you can pass the frozen argument to the @dataclass decorator on the definition of Employee: Python >>> @dataclass(frozen=True) ... class Employee: ...

Tuples have many uses in Python programming. 一个特别重要的用例是当您希望从Python函数返回多个对象时。 One especially important use case is when you want to return more than one object from your Python function. 在这种情况下,您通常会将所有这些对象包装在一个元组对象中,然后返回该元组。 In that...
Python also includes thetuplemethod for explicitly creating a tuple. tuple2 = tuple(0.11, 88, 'test', 'test', -477.62); It is also possible to create an empty tuple in Python. For this, you simply pass in a set of empty parentheses. ...
We defined a tuple namedtuple_namesand a list namedlist_names. In the tuple definition, we used parenthesis()while in the list definition, we used square brackets[]. Python'stype()method helps easily identify the type of an object:
