Python program to concatenate maximum tuples

Method 1:

A method to concatenate maximum value tuple string is by finding the tuples from the list with maximum value and then joining their string values.

To find max value, we will be using max() method and itemgetter to get value from tuple. Then using list comprehension we will find all values with value equal to max. And then using the join method we will concatenate the values.

Program:

# Python Program to concatenate Maximum Tuples
from operator import itemgetter

# Creating and printing list of tuples 
tupList = [("python", 7), ("learn" , 1), ("programming", 7), ("code" , 3)]
print("List of Tuples : " + str(tupList))

# Concatenating maximum tuple 
maxVal = max(tupList, key=itemgetter(1))[1]
concString = ' '.join([key for key, ele in tupList if ele == maxVal])

# Printing concatenated string 
print("Maximum concatenated string from list : " + str(concString))

Output:

List of Tuples : [('python', 7), ('learn', 1), ('programming', 7), ('code', 3)]
Maximum concatenated string from list : python programming

Method 2:

An Alternative way to perform the task is using the filter method to separate max value string for joining to perform concatenation.

Program:

# Python Program to concatenate Maximum Tuples
from operator import itemgetter

# Creating and printing list of tuples 
tupList = [("python", 7), ("learn" , 1), ("programming", 7), ("code" , 3)]
print("List of Tuples : " + str(tupList))

# Concatenating maximum tuple 
maxVal = max(tupList, key=itemgetter(1))[1]
concString = " ".join([ele[0] for ele in filter(lambda ele: ele[1] == maxVal, tupList)])

# Printing concatenated string 
print("Maximum concatenated string from list : " + str(concString))

Output:

List of Tuples : [('python', 7), ('learn', 1), ('programming', 7), ('code', 3)]
Maximum concatenated string from list : python programming
