How to Change Tuple Values in Python?
As mentioned above, Python tuples are immutable. This implies that they can’t be changed, added to, or removed after they’ve been created. Tuple values cannot be changed. However, you can convert a tuple into a list to be able to change it. Example: Output: (“cranberry”, “avacado”, “apricot”) How to Add Tuple Values in Python? Tuples…

How to Slice Tuples in Python?
You must use the [] operator on a tuple to index or slice it. If you supply a positive integer while indexing a tuple, it pulls that index from the tuple counting from the left. If the index is negative, it is retrieved from the tuple counting from the right. Python Tuple Slicing Example: Output:…

How to Access Items in a Tuple?
The index number, enclosed in square brackets, can be used to retrieve Python tuple items: Example:

What are Tuples in Python?
Python tuples are immutable. This implies that they can’t be changed, added to, or removed after they’ve been created. There are, however, a few workarounds. The use of tuples in Python is to save more than one item in a single variable. It is a kind of data type that allows data storage. Another important…

Understanding List Methods in Python
All the Python List methods are as listed below: 1. clear(): To delete all items from the list. Code: Output:[] 2. copy(): To return a shallow copy of the list. Code: Output:[“python”, “web”, “wscube”] 3. count(): To return the count of the element in the list. Code: Output: 1 4. extend(): This function is used to…

How to Create a Nested List in Python?
A nested list is made up of a series of sublists separated by commas. Example: How to Access Nested List Items by Index? The following are the indices for the entries in a nested list: Output: [‘c’, ‘d’, [‘e’, ‘f’]] print(List1[2][2]) Output: [‘e’, ‘f’] print(List1[2][2][0]) Output: e Negative List Indexing In a Nested List Negative…

Understanding List Comprehension in Python
Iterables like tuples, strings, arrays, and lists are used to build new lists using list comprehensions.List comprehension in Python consists of brackets that carry the expression for each element, as well as a for loop that iterates across every element. Example: Output: [1, 9, 25, 49, 81]

How to Iterate a Python List?
Using a For loop, you can iterate over a list in Python. Example: Output: pear melon orange Loop Through the Index Number You can also use the index number to loop through a list in Python. To make an appropriate iterable, use the range() and len() functions. Example: Output: pear melon orange Using a While…

How to Slice a List in Python?
Slice operation is done on lists with the use of a colon(:). If you want to print elements from beginning to a range, use [: Index]. To print elements from the end, use [:-Index]. Alternatively, if you want to print elements from a specific Index till the end, use [Index:]. To print elements within a…

How to Delete or Remove Elements From a List in Python?
There are two main ways to remove elements from a Python list. We have discussed both ways below with examples: 1. Using pop() function in Python The pop() method is used to remove & return an element from a set. By default, it merely eliminates the last element. It provides the element’s index as an input to…
