Python | Check if element is present in tuple

  • Last Updated : 26 Nov, 2019

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
