Find the Maximum of Similar Indices in two list of Tuples in Python
If it is required to find the maximum of the similar indices in two list of tuples, the 'zip' method and list comprehension can be used.
The list comprehension is a shorthand to iterate through the list and perform operations on it.
The zip method takes iterables, aggregates them into a tuple, and returns it as the result.
A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).
A list of tuple basically contains tuples enclosed in a list.
Below is a demonstration of the same −
Example
my_list_1 = [( 67, 45), (34, 56), (99, 123)]
my_list_2 = [(10, 56), (45, 0), (100, 12)]
print ("The first list is : " )
print(my_list_1)
print ("The second list is : " )
print(my_list_2)
my_result = [(max(x[0], y[0]), max(x[1], y[1]))
for x, y in zip(my_list_1, my_list_2)]
print("The maximum value among the two lists is :")
print(my_result)Output
The first list is : [(67, 45), (34, 56), (99, 123)] The second list is : [(10, 56), (45, 0), (100, 12)] The maximum value among the two lists is : [(67, 56), (45, 56), (100, 123)]
Explanation
- The two lists of tuples are defined, and are displayed on the console.
- The 'zip' method is used to combine both the list of tuples, and the 'max' method is used to fetch the maximum value among the tuples.
- This is converted to a list.
- This operation is assigned a variable.
- This variable is the output that is displayed on the console.
