Which of the following is true about the python tuple items
A tuple in Python is similar to a list. The difference between the two is that we cannot change the elements of a tuple once it is assigned whereas we can change the elements of a list. Show
Creating a TupleA tuple is created by placing all the items (elements) inside parentheses A tuple can have any number of items and they may be of different types (integer, float, list, string, etc.).
Output () (1, 2, 3) (1, 'Hello', 3.4) ('mouse', [8, 4, 6], (1, 2, 3)) A tuple can also be created without using parentheses. This is known as tuple packing.
Output (3, 4.6, 'dog') 3 4.6 dog Creating a tuple with one element is a bit tricky. Having one element within parentheses is not enough. We will need a trailing comma to indicate that it is, in fact, a tuple.
Output Access Tuple ElementsThere are various ways in which we can access the elements of a tuple. 1. IndexingWe can use the index operator So, a tuple having 6 elements will have indices from 0 to 5. Trying to access an index
outside of the tuple index range(6,7,... in this example) will raise an The index must be an integer, so we cannot use float or other types. This will result in Likewise, nested tuples are accessed using nested indexing, as shown in the example below.
Output p t s 4 2. Negative IndexingPython allows negative indexing for its sequences. The index of -1 refers to the last item, -2 to the second last item and so on.
Output t p 3. SlicingWe can access a range of items in a tuple by using the slicing operator colon
Output ('r', 'o', 'g') ('p', 'r') ('i', 'z') ('p', 'r', 'o', 'g', 'r', 'a', 'm', 'i', 'z') Slicing can be best visualized by considering the index to be between the elements as shown below. So if we want to access a range, we need the index that will slice the portion from the tuple. Element Slicing in PythonChanging a TupleUnlike lists, tuples are immutable. This means that elements of a tuple cannot be changed once they have been assigned. But, if the element is itself a mutable data type like a list, its nested items can be changed. We can also assign a tuple to different values (reassignment).
Output (4, 2, 3, [9, 5]) ('p', 'r', 'o', 'g', 'r', 'a', 'm', 'i', 'z') We can use We can also repeat the elements in a tuple for a given number of times using the Both
Output (1, 2, 3, 4, 5, 6) ('Repeat', 'Repeat', 'Repeat') Deleting a TupleAs discussed above, we cannot change the elements in a tuple. It means that we cannot delete or remove items from a tuple. Deleting a tuple entirely, however, is possible using the keyword del.
Output Traceback (most recent call last): File " Tuple MethodsMethods that add items or remove items are not available with tuple. Only the following two methods are available. Some examples of Python tuple methods:
Output 2 3 Other Tuple Operations1. Tuple Membership TestWe can test if an item exists in a tuple or not, using the keyword
Output True False True 2. Iterating Through a TupleWe can use a
Output Hello John Hello Kate Advantages of Tuple over ListSince tuples are quite similar to lists, both of them are used in similar situations. However, there are certain advantages of implementing a tuple over a list. Below listed are some of the main advantages:
What is true about tuples in Python?Python Tuple is a collection of objects separated by commas. In some ways, a tuple is similar to a list in terms of indexing, nested objects, and repetition but a tuple is immutable, unlike lists which are mutable.
Which of the following is true about tuples?Explanation: Tuples are immutable and don't have an append method.
What is tuple items in Python?Tuple. Tuples are used to store multiple items in a single variable. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and unchangeable.
Does tuple allow duplicates in Python?31.2 Python Collection Types
Tuples A Tuple represents a collection of objects that are ordered and immutable (cannot be modified). Tuples allow duplicate members and are indexed.
