How to Check if Tuple is empty in Python ?

Python – Check if element is present in tuple

Last Updated : 19 Feb, 2025

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.

Python - Check if any list element is present in Tuple

Given a tuple, check if any list element is present in it. Input : test_tup = (4, 5, 10, 9, 3), check_list = [6, 7, 10, 11] Output : True Explanation : 10 occurs in both tuple and list. 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
