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']
