Python | Check if element is present in tuple

Sometimes, while working with data, we can have a problem in which we need to check if data we are working with has a particular element. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using loop
This is brute force method to perform this task. In this, we iterate through the tuple and check each element if it’s our, if found we return True.

# Python3 code to demonstrate working of 
# Check if element is present in tuple 
# using loop 
  
# initialize tuple 
test_tup = (10, 4, 5, 6, 8) 
  
# printing original tuple 
print("The original tuple : " + str(test_tup)) 
  
# initialize N  
N = 6
  
# Check if element is present in tuple 
# using loop 
res = False 
for ele in test_tup : 
    if N == ele : 
        res = True
        break
  
# printing result 
print("Does tuple contain required value ? : " + str(res)) 

Output :

The original tuple : (10, 4, 5, 6, 8)
Does tuple contain required value ? : True

Method #2 : Using in operator
Using in operator is most Pythonic way to perform this task. It is a one-liner and recommened to perform this task.

# Python3 code to demonstrate working of 
# Check if element is present in tuple 
# Using in operator 
  
# initialize tuple 
test_tup = (10, 4, 5, 6, 8) 
  
# printing original tuple 
print("The original tuple : " + str(test_tup)) 
  
# initialize N  
N = 6
  
# Check if element is present in tuple 
# Using in operator 
res = N in test_tup 
  
# printing result 
print("Does tuple contain required value ? : " + str(res)) 

Output :

The original tuple : (10, 4, 5, 6, 8)
Does tuple contain required value ? : True
