Explanation:
Find the tuples containing the given element from a list of tuples in Python

# Python Program to input a list of 5 elements and search element in List

mylist = [] print("Enter 5 elements for the list: ") for i in range(5): value = int(input()) mylist.append(value) print("Enter an element to be search: ") element = int(input()) for i in range(5): if element == mylist[i]: print("\nElement found at Index:", i) print("Element found at Position:", i+1)

Output:

Enter 5 elements for the list: 45 34 37 34 55 Enter an element to be search: 34 ('\nElement found at Index:', 1) ('Element found at Position:', 2) ('\nElement found at Index:', 3) ('Element found at Position:', 4) >>>

Python | Find the tuples containing the given element from a list of tuples

Given a list of tuples, the task is to find all those tuples containing the given element, say n.
Examples:

Input: n = 11, list = [(11, 22), (33, 55), (55, 77), (11, 44)]
Output: [(11, 22), (11, 44)]
Input: n = 3, list = [(14, 3),(23, 41),(33, 62),(1, 3),(3, 3)]
Output: [(14, 3), (1, 3), (3, 3)]

There are multiple ways we can find the tuples containing the given element from a list of tuples. Let’s see some of Pythonic ways to do this task.
Method #2: Using list comprehension. It works only when there are fixed number of elements in every list. For example 2 elements in below code.

Python3

# Python code to find the tuples containing
# the given element from a list of tuples
# List of tuples

Input = [(14, 3),(23, 41),(33, 62),(1, 3),(3, 3)]
# Find an element in list of tuples.

Output = [item for item in Input

if item[0] == 3 or item[1] == 3]
# printing output

print(Output)

Output: [(14, 3), (1, 3), (3, 3)]

Method #1 : Using filter In this solution, there can be variable number of nodes in lists.

Python3

# Python code to find the tuples containing
# the given element from a list of tuples
# List of tuples

Input = [(11, 22), (33, 55), (55, 77),

(11, 44), (33, 22, 100, 11), (99, 11)]
# Using filter

Output = list(filter(lambda x:11 in x, Input))
# Printing output

print(Output)

Output: [(11, 22), (11, 44), (33, 22, 100, 11), (99, 11)]

Code:

# Python code to find the tuples containing # the given element from a list of tuples # List of tuples Input = [(14, 3),(23, 41),(33, 62),(1, 3),(3, 3)] # Find an element in list of tuples. Output = [item for item in Input if item[0] == 3 or item[1] == 3] # printing output print(Output)

Explanation:

Here first a list of tuple is entered with list as elements.
Then the condition is checked whether the first or second one of list is equal to 3.
If it is equal to 3 then it is presented as output in tuple containing list.

Output:

[(14, 3), (1, 3), (3, 3)]

Thank you for learning from this post. We wish all of the best for class 11 computer science with python exams. Python is one of the most easiest and powerful language. I am impressed that CBSE is teaching Python. I feel if you go into information and communication field your carrier will be secured. Python is mainly used in data analysis and artificial intelligence programs and software’s. With the whole new generation of students in CBSE board learning Python it gives me pride to devote time for solving and presenting the work. This practical file questions are solved by Experts and every day Programmers. Here we have presented the code in most simple way of programming and yet the most powerful code for our practical. For securing full marks bookmark this website as it will help you to sail through Practicals, projects and pythons questions and answers of CBSE computer science (Python.. I am sure computer science work is nice and benefit the learners. Here below whole practical Practical file is given with link.

A list can have tuples as its elements. In this article we will learn how to identify those tuples which contain a specific search element which is a string.
