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 −ExampleLive Demomy_list_1 = [( 67, 45), ...

A list in Python is a linear data structure where elements are stored in contiguous memory locations and elements are accessed by their indexes.We may sometimes need to remove an element from a list in Python. There are various inbuilt functions to achieve this.pop()This deletes or removes the element at the index passed as an argument in pop().Example Live Demolst=[1, 2, 3, 4, 5] lst.pop(2) print(lst)Output[1, 2, 4, 5]The above code snippet shows that the pop(2) removes the element at index 2.remove()This function removes the first occurrence of the element passed as argument in remove().Example Live Demolst=[1, 2, 3, 2, 4, 5] ...

If it is required to check if a tuple contains a specific value 'K', it can be done using the 'any' method, the 'map' method and the lambda function.Anonymous function is a function which is defined without a name. In general, functions in Python are defined using 'def' keyword, but anonymous function is defined with the help of 'lambda' keyword. It takes a single expression, but can take any number of arguments. It uses the expression and returns the result of it.The map function applies a given function/operation to every item in an iterable (such as list, tuple). It returns ... Read More
If it is required to get the combinations of sum with respect to tuples in a list of tuples, the 'combinations' method and the list comprehension can be used.The 'combinations' method returns 'r' length subsequence of elements from the iterable that is passed as input. The combinations are shown in lexicographic sort order. The combination tuples are displayed in a sorted order.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 ...

A queue is a linear data structure that works on the First In First Out mechanism(FIFO).The element which enters first in the queue is the first to be processed.ExampleThe queue data structure can be understood with the help of a queue at a bus stand. The person who reaches first at the bus stand is the first person in the queue and other persons stand him as they reach the bus stand. When the bus arrives, the person who reached first at the bus stand will be the first person to enter the bus and the rest will enter in ... Read More
If it is required to perform pairwise addition in tuples, then the 'zip' method, the 'tuple' method and a generator expression can be used.The zip method takes iterables, aggregates them into a tuple, and returns it as the result.Generator is a simple way of creating iterators. It automatically implements a class with '__iter__()' and '__next__()' methods and keeps track of the internal states, as well as raises 'StopIteration' exception when no values are present that could be returned.The 'tuple' method converts a given iterable into tuple data type.Below is a demonstration of the same −ExampleLive Demomy_tuple = ( 67, 45, ...

If the modulo of tuple elements is required to be determined, the 'zip' method and a generator expression can be used.Generator is a simple way of creating iterators. It automatically implements a class with '__iter__()' and '__next__()' methods and keeps track of the internal states, as well as raises 'StopIteration' exception when no values are present that could be returned.The zip method takes iterables, aggregates them into a tuple, and returns it as the result.Below is a demonstration of the same −ExampleLive Demomy_tuple_1 = ( 67, 45, 34, 56) my_tuple_2 = (99, 123, 10, 56) print ("The first tuple ...

A dictionary is a data structure that consists of key and value pairs. We can sort a dictionary using two criteria −Sort by key − The dictionary is sorted in ascending order of its keys. The values are not taken care of.Sort by value − The dictionary is sorted in ascending order of the values.Method 1 − Sort the dictionary by keyIn this approach, the dictionary is sorted in ascending order of its keys.Input:{2:90, 1: 100, 8: 3, 5: 67, 3: 5}Output:{1:100, 2:90, 3:5, 5:67, 8:3}As shown above, we can see the dictionary is sorted according to its keys.Example Live Demodic={2:90, ...

If it is required to extract the rear element from a list of tuples, it can be done using list comprehension and negative indexing.The list comprehension is a shorthand to iterate through the list and perform operations on it.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 −ExampleLive Demomy_list = [('Will', 67, 45), ('Jam', 34, 56), ('Pow', 99, 123), ('Nyk', 0, 56)] print ("The list of tuples is : ...

Bubble sort is a sorting algorithm to sort a list into ascending (or descending) order. This is the easiest sorting algorithm but it is not very efficient. It can be used on small input sizes but not time efficient for lists or arrays with larger length. Its time complexity is O(n^2). However, this is an in-place sorting algorithm, which means it doesn’t use any extra space. Thus, its efficient in terms of space complexity. However, it is not used much since there are better sorting algorithms than bubble sort.How does Bubble Sort work?In bubble sort, two for loops are used. ... Read More
