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 the 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
# 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
It is used to perform this task. It is a one-liner and recommended to perform this task.
Python3
# 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
Method: Using list comprehension method
Python3
t = ( 10 , 4 , 5 , 6 , 8 ); n = 6 x = [i for i in t if i = = n] print ([ "yes" if x else "no" ]) |
Output
['yes']
