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
