The document provides an overview of tuples in Python, highlighting their characteristics as immutable data types similar to lists, along with methods for accessing, changing, and deleting tuples. It also compares tuples and lists, emphasizing their usage, flexibility, and the functionality of the tuple constructor. Additionally, the document briefly discusses concepts like indexing, slicing, and web crawlers in relation to data collection.

- 4. www.edureka.co/python A tuple is an immutable data type in python, almost similar to a list in python in terms of indexing and having duplicate members. It is a collection data type that stores python objects separated by commas.
- 6. Accessing Elements In A Tuple www.edureka.co/python • A web-crawler is also known as a web spider, automatic indexer or simply crawler. • It is an internet bot that helps in web indexing • Web crawlers helps in collecting information from a webpage and the links related to them • It also helps in validating HTML code and hyperlinks. • They crawl one page at a time until all the pages are indexed. Indexing It is a data structure technique to effectively retrieve information from a data structure. In python, several data types support indexing Slicing is a technique in which we use the slicing operator ‘:’ to get a range of elements from a tuple or any other data type that supports indexing for accessing elements.
- 8. Changing A Tuple www.edureka.co/python To install scrapy, simply run the following command in the command prompt or in the terminal, or simply you can add the package from the project interpreter too.Even though tuples in python are immutable in nature, a nested object in a tuple can be changed. Or in general, a tuple in python can be reassigned with a different value.
- 10. Joining two tuples is a very easy task. You just to assign the addition of the two tuples to another variable and it will return the concatenated tuple with the values of both the tuples Concatenating Two Tuples www.edureka.co/python
- 12. Deleting A Tuple www.edureka.co/python Being an immutable data type, a tuple in python does not allow any changes and you cannot even remove an element from a tuple after the declaration. But there is a keyword ‘del’ which will delete the tuple altogether.
- 14. Tuple Methods www.edureka.co/python • Returns the count of the elementCount • Returns the index number of the element Index
- 16. List vs Tuple www.edureka.co/python •Used for homogenous data types •Mutable in nature •Does not have immutable elements •No guarantee that the data is write-protected •Generally used for heterogeneous data types •Immutable in nature, which helps in faster iteration •Immutable elements can be used as a key for a dictionary •Implementing a tuple with data that does not change guarantees that it is write-protected
- 18. Tuple Constructor www.edureka.co/python • It is possible to create a tuple using a tuple() constructor as well. We can even use the tuple constructor to change a list to a tuple.
