We passed the second item in each tuple to the len() function to get the string's length. The function you provide for the key argument can be used to get the min and max values according to different criteria. # Find Min and Max values in a list of tuples using itemgetter You can...
1. Using the max() function Themax()function in Python returns the largest item in an iterable. You can use this function to find the longest string in a list by passing the list as an argument: fruits=['apple','banana','American elderberry','pomegranate']longest_string=max(fruits,key...
