Python | Count the elements in a list until an element is a Tuple

In this problem, we need to accept a list. The list can have nested tuples. We need to count the elements in a list until a tuple has been encountered. Examples: Input : [4, 5, 6, 10, (1, 2, 3), 11, 2, 4] Output : 4 Input : [4, (5, 6), 10, (1, 2, 3), 11, 2, 4] Output : 1 Method #1: In this program we will use the concept of isinstance() to verify w

Python | Count occurrences of an element in a Tuple

In this program, we need to accept a tuple and then find the number of times an item is present in the tuple. This can be done in various ways, but in this article, we will see how this can be done using a simple approach and how inbuilt functions can be used to solve this problem. Examples: Tuple: (10, 8, 5, 2, 10, 15, 10, 8, 5, 8, 8, 2)Input : 4

Python | Sort a tuple by its float element

In this article, we will see how we can sort a tuple (consisting of float elements) using its float elements. Here we will see how to do this by using the built-in method sorted() and how can this be done using in place method of sorting. Examples: Input : tuple = [('lucky', '18.265'), ('nikhil', '14.107'), ('akash', '24.541'), ('anand', '4.256'),

Python | Reversing a Tuple

As we know that in Python, tuples are immutable, thus it cannot be changed or altered. This provides us with limited ways of reversing a tuple, unlike a list. We will go through few techniques on how a tuple in python can be reversed. Examples: Input : tuples = ('z','a','d','f','g','e','e','k') Output : ('k', 'e', 'e', 'g', 'f', 'd', 'a', 'z') Inpu

Unpacking a Tuple in Python

Python Tuples In python tuples are used to store immutable objects. Python Tuples are very similar to lists except to some situations. Python tuples are immutable means that they can not be modified in whole program. Packing and Unpacking a Tuple: In Python, there is a very powerful tuple assignment feature that assigns the right-hand side of value

Python | Ways to iterate tuple list of lists

List is an important container and used almost in every code of day-day programming as well as web-development, more it is used, more is the requirement to master it and hence knowledge of its operations is necessary.Given a tuple list of lists, write a Python program to iterate through it and get all elements. Method #1: Use itertools.ziplongest C

Python | Find whether all tuple have same length

Given a list of tuples, the task is to find whether all tuple have same length. Below are some ways to achieve the above task. Method #1: Using Iteration C/C++ Code # Python code to find whether all # tuple have equal length # Input List initialization Input = [(11, 22, 33), (44, 55, 66)] # printing print("Initial list of tuple", Input) #

Python | Convert list of tuple into dictionary

Given a list containing all the element and second list of tuple depicting the relation between indices, the task is to output a dictionary showing the relation of every element from the first list to every other element in the list. These type of problems are often encountered in Coding competition. Below are some ways to achieve the above task. I

Python | Remove Consecutive tuple according to key

Sometimes, while working with Python list, we can have a problem in which we can have a list of tuples and we wish to remove them basis of first element of tuple to avoid it's consecutive duplication. Let's discuss certain way in which this problem can be solved. Method : Using groupby() + itemgetter() + next() This task can be performed using comb

Evaluate a Hermite series at tuple of points x in Python

In this article, we will be looking toward the approach to evaluating a Hermite series at a tuple of points x in Python and NumPy. Example Tuple: (6,7,8,9,10) Result: [102175. 191631. 329175. 529399. 808815.] Explanation: Hermite series at points x.
