In this example, the zip() function pairs the student names from the “students” list with their corresponding grades from the “grades” list which results in a dictionary where each student is associated with their respective grade.
Input: tupList = [("python", 7), ("learn" , 1), ("programming", 7), ("code" , 3)] Output: "python programming" To perform maximum concatenation, we need to find all maximum value tuples and then concatenate their string values. Python provides multiple options to perform the task...
