When it is required to join tuples if they contain a similar initial element, a simple ‘for’ loop and an ‘of’ condition can be used. To store elements to one list, the ‘extend’ method can be used.Below is the demonstration of the same −Example Live Demomy_list = [(43, 15), (66, 98), (64, 80), (14, 9), (47, 17)] print("The list is : ") print(my_list) my_result = [] for sub in my_list:    if my_result and my_result[-1][0] == sub[0]:       my_result[-1].extend(sub[1:])    else:       my_result.append([ele for ele in sub]) my_result = list(map(tuple, my_result)) print("The extracted elements ...

In Python, both tuples and lists are used to store data in sequence. Python provides built-in functions and operators that allow us to easily add elements of a tuple into a list and elements of a list into a tuple. In this article, we will explain various methods to perform these conversions, along with example codes. Scenario 1 You are given a list and a tuple as input, your task is to add tuple into the list and print the list as output. For example: # Input List and Tuple my_list = [3, 6, 9, 45, 66] my_tup = ... Read More

When it is required to create a list from a given list that have a number and its cube, the list comprehension can be used.Below is the demonstration of the same −Example Live Demomy_list = [32, 54, 47, 89] print("The list is ") print(my_list) my_result = [(val, pow(val, 3)) for val in my_list] print("The result is ") print(my_result)OutputThe list is [32, 54, 47, 89] The result is [(32, 32768), (54, 157464), (47, 103823), (89, 704969)]ExplanationA list is defined, and is displayed on the console.The list comprehension is used to iterate through the list, and use the ‘pow’ method to get ...

When it is required to find the maximum and minimum K elements in a tuple, the ‘sorted’ method is used to sort the elements, and enumerate over them, and get the first and last elements.Below is the demonstration of the same −Example Live Demomy_tuple = (7, 25, 36, 9, 6, 8) print("The tuple is : ") print(my_tuple) K = 2 print("The value of K has been initialized to ") print(K) my_result = [] my_tuple = list(my_tuple) temp = sorted(my_tuple) for idx, val in enumerate(temp):    if idx < K or idx >= len(temp) - K:       ...

When it is required to find the keys associated with specific values in a dictionary, the ‘index’ method can be used.Below is the demonstration of the same −Example Live Demomy_dict ={"Hi":100, "there":121, "Mark":189} print("The dictionary is :") print(my_dict) dict_key = list(my_dict.keys()) print("The keys in the dictionary are :") print(dict_key) dict_val = list(my_dict.values()) print("The values in the dictionary are :") print(dict_val) my_position = dict_val.index(100) print("The value at position 100 is : ") print(dict_key[my_position]) my_position = dict_val.index(189) print("The value at position 189 is") print(dict_key[my_position])OutputThe dictionary is : {'Hi': 100, 'there': 121, 'Mark': 189} The keys in the dictionary are : ...

When it is required to check if the frequency of a dictionary, set and counter are same, the Counter package is imported and the input is converted into a ‘Counter’. The values of a dictionary are converted to a ‘set’ and then to a list. Based on the length of the input, the output is displayed on the console.Below is the demonstration of the same −Example Live Demofrom collections import Counter def check_all_same(my_input):    my_dict = Counter(my_input)    input_2 = list(set(my_dict.values()))    if len(input_2)>2:       print('The frequencies are not same')    elif len (input_2)==2 and input_2[1]-input_2[0]>1:       ...
