Report

We are given a tuple and our task is to find whether given element is present in tuple or not. For example x = (1, 2, 3, 4, 5) and we need to find if 3 is present in tuple so that in this case resultant output should be True.

Using in Operator

in operator checks if an element is present in a tuple by iterating through its items. It returns True if the element is found and False otherwise making it a simple and efficient membership check.

Python

x = (1, 2, 3, 4, 5) # Check if the element '3' is present in the tuple res = 3 in x print(res)

Output

True

Explanation:

in operator checks if the element 3 is present in tuple x.
If element is found it returns True; otherwise it returns False

Using index()

index() method returns the position of the first occurrence of an element in a tuple. If the element is not found it raises a ValueError so it’s often used with exception handling.

Python

t = (1, 2, 3, 4, 5)  try:     index = t.index(3)      res = True  # If '3' is found except ValueError:     res = False  # If '3' is not found  print(res)

Output

True

Explanation:

t.index(3) searches for the element 3 in the tuple t and returns its index if found.
If element is not found a ValueError is raised which is caught to set result to False.

Using a Loop

Using a loop we can iterate through each element of the tuple to check for a match. If target element is found we return True otherwise we return False after checking all elements.

Python

t = (1, 2, 3, 4, 5)   ele = 3   res = False   for item in t:       # Check if the current element matches     if item == ele:            res = True           break   print(res)

Output

True

Explanation:

Loop checks each element in the tuple for equality with ele. If a match is found res is set to True.
Break statement stops further iteration once the element is found improving efficiency.

Input : test_tup = (4, 5, 12, 9, 3), check_list = [6, 7, 10, 11] Output : False Explanation : No common elements.

Python | Check if element is present in tuple of tuples

Sometimes the data that we use is in the form of tuples and often we need to look into the nested tuples as well. The common problem that this can solve is looking for missing data or na value in data preprocessing. Let's discuss certain ways in which this can be performed. Method #1: Using any() an

Test if all elements are present in list-Python

The task of testing if all elements are present in a list in Python involves checking whether every item in a target list exists within a reference list. For example, given two lists a = [6, 4, 8, 9, 10] and b = [4, 6, 9], the task is to confirm that all elements in list b are also found in list a.

How to Check if Tuple is empty in Python ?

A Tuple is an immutable sequence, often used for grouping data. You need to check if a tuple is empty before performing operations. Checking if a tuple is empty is straightforward and can be done in multiple ways. Using the built-in len() will return the number of elements in a tuple and if the tupl

Python | Filter tuples according to list element presence

Sometimes, while working with records, we can have a problem in which we have to filter all the tuples from a list of tuples, which contains atleast one element from a list. This can have applications in many domains working with data. Let's discuss certain ways in which this task can be performed.

Python - Check if all elements in List are same

To check if all items in list are same, we have multiple methods available in Python. Using SetUsing set() is the best method to check if all items are same in list. [GFGTABS] Python a = [3, 3, 3, 3] # Check if all elements are the same result = len(set(a)) == 1 print(result) [/GFGTABS]OutputTrue Ex

Python - Check if Tuple contains only K elements

Sometimes, while working with Python tuples, we can have a problem in which we need to test if any tuple contains elements from set K elements. This kind of problem is quite common and have application in many domains such as web development and day-day programming. Let's discuss certain ways in whi

Given a list of lists, the task is to determine whether the given element exists in any sublist or not. Given below are a few methods to solve the given task. Method #1: Using any() any() method return true whenever a particular element is present in a given iterator. C/C++ Code # Python code to dem

Python - Check if List contains elements in Range

Checking if a list contains elements within a specific range is a common problem. In this article, we will various approaches to test if elements of a list fall within a given range in Python. Let's start with a simple method to Test whether a list contains elements in a range. Using any() Function

Python | Check if any element occurs n times in given list

Given a list, the task is to find whether any element occurs 'n' times in given list of integers. It will basically check for the first element that occurs n number of times. Examples: Input: l = [1, 2, 3, 4, 0, 4, 3, 2, 1, 2], n = 3 Output : 2 Input: l = [1, 2, 3, 4, 0, 4, 3, 2, 1, 2, 1, 1], n = 4
