Python | Compare tuples

Sometimes, while working with records, we can have a problem in which we need to check if each element of one tuple is greater/smaller than it’s corresponding index in other tuple. This can have many possible applications. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using all() + generator expression + zip()
The combination of above functionalities can be used to perform this task. In this, we just compare all elements using all(). The cross tuple access is done by zip() and generator expression gives us the logic to compare.

# Python3 code to demonstrate working of
# Comparing tuples
# using generator expression + all() + zip()

# initialize tuples
test_tup1 = (10, 4, 5)
test_tup2 = (13, 5, 18)

# printing original tuples
print("The original tuple 1 : " + str(test_tup1))
print("The original tuple 2 : " + str(test_tup2))

# Comparing tuples
# using generator expression + all() + zip()
res = all(x < y for x, y in zip(test_tup1, test_tup2))

# printing result
print("Are all elements in second tuple greater than first ? : " + str(res))

Output :

The original tuple 1 : (10, 4, 5)
The original tuple 2 : (13, 5, 18)
Are all elements in second tuple greater than first ? : True

Method #2 : Using all() + map() + lambda
The combination of above functionalities can be used to perform this particular task. In this, we perform extension of logic to each element using map() and logic generation by lambda function.

# Python3 code to demonstrate working of
# Comparing tuples
# using all() + lambda + map()

# initialize tuples
test_tup1 = (10, 4, 5)
test_tup2 = (13, 5, 18)

# printing original tuples
print("The original tuple 1 : " + str(test_tup1))
print("The original tuple 2 : " + str(test_tup2))

# Comparing tuples
# using all() + lambda + map()
res = all(map(lambda i, j: i < j, test_tup1, test_tup2))

# printing result
print("Are all elements in second tuple greater than first ? : " + str(res))

Output :

The original tuple 1 : (10, 4, 5)
The original tuple 2 : (13, 5, 18)
Are all elements in second tuple greater than first ? : True
