When it is required to filter the tuples by the 'K'th element from a list, list comprehension and 'in' operators can be used.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. The 'in' operators checks to see if the specific data is present in the iterable/data or not.The list comprehension is a shorthand to iterate through the list and perform operations on it.Below is a demonstration of the same −ExampleLive Demomy_list = [(1, 21), (25, 'abc', ...

We can develop games in Python using PyGame. PyGame is a Python module that is used to develop games. This module includes computer graphics and sound libraries used in video game development.Install PyGameTo develop game in Python, we need PyGame. Therefore, we need to install PyGame.We should Python and pip preinstalled on our system before installing PyGame.Open the terminal and type the following command to install PyGame.py -m pip install -U pygame --userImport PyGameThe PyGame module needs to be imported in Python IDE before writing the program for the game. There is some common code that includes displaying the pygame ... Read More

When it is required to perform tuple division in Python, the 'zip' method and generator expressions 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.Below is a demonstration of the same −ExampleLive Demomy_tuple_1 = ( 7, 8, 3, 4, 3, 2) my_tuple_2 = (9, 6, 8, 2, 1, 4) print ("The ...

The list is a linear data structure containing data elements.Example1, 2, 3, 4, 5, 6Dictionary is a data structure consisting of key: value pairs. Keys are unique and each key has some value associated with it.Example1:2, 3:4, 5:6Given a list, convert this list into the dictionary, such that the odd position elements are the keys and the even position elements are the values as depicted in the above example.Method 1 − Iterating over the listExample Live Demodef convert(l):    dic={}    for i in range(0, len(l), 2):       dic[l[i]]=l[i+1]    return dic ar=[1, 'Delhi', 2, 'Kolkata', 3, ...

When it is required to perform 'XOR' operations on the elements of one tuple, the 'zip' method and the 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.Below is a demonstration of the same −ExampleLive Demomy_tuple_1 = ( 7, 8, 3, 4, 3, 2) my_tuple_2 = (9, 6, 8, 2, ...

When it is required to raise the elements of one tuple, as a power of another tuple, the 'zip' method and the 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.Below is a demonstration of the same −ExampleLive Demomy_tuple_1 = ( 7, 8, 3, 4, 3, 2) my_tuple_2 = (9, ...

When it is required to concatenate two string tuples, the 'zip' method and the 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.Below is a demonstration of the same −ExampleLive Demomy_tuple_1 = ('Jane', 'Pink', 'El') my_tuple_2 = ('Will', 'Mark', 'Paul') print ("The first tuple is : " ) print(my_tuple_1) ...

Converting Text to Speech basically refers to a program where you give input as a text and the output you receive is the input text in the form of a speech.Python offers the text to speech conversion with the help of APIs. One such API which serves this purpose is the Google Text to Speech API , known as gTTS. The gTTS enables to conversion the provided text into speech and save the output as audio.Step 1 − Install gTTSTo use the gTTS Text to speech conversion tool, we need to install it first. Installing the gTTS is pretty easy.Open ... Read More
