Python Code: # Define a list 'x' containing tuples, where each tuple has two elementsx=[(4,1),(1,2),(6,0)]# Use the 'min' function to find the minimum element in the list 'x' based on a custom key# The 'key' argument specifies a lambda function that calculates a key for ...
When a list contains two "Delhi" then the index() finds the "Delhi" when found it will end itself, and will not search for further elements but in the second method, it will start checking from starting to last element even the "Delhi" is found or not when "Delhi" found then it wi...
When initializing aCounterobject, you can pass an iterable (such as a list, tuple, or string) or a dictionary as an argument. If an iterable is provided,Counterwill count the occurrences of each unique element in the iterable. We can access the count of a specific element using indices, ...

In Python, tuples are a data structure that allows you to store multiple values in a single variable. Tuples are useful for storing data that is organized in a specific way, such as a list of items or a set of values. To use tuples in your code, you first need to create a tuple...
The.most_common()method of theCounterclass returns a list containing two-item tuples with each unique element and its frequency. Basic Syntax: fromcollectionsimportCounter# Create a Counter object from an iterablecounter_object=Counter(iterable) ...
2. Find the Maximum Value of List Using max() Function You can use themax()function to find the maximum value in a list. It takes an iterable(such as list,string,tuple, or,set) as its argument and returns the largest element from that iterable. For example, first, initialize a list...
