Python Program to Determine all Pythagorean Triplets in the Range
When it is required to determine the Pythagorean triplets within a given range, a method is defined, that helps calculate the triplet values.Below is the demonstration of the same −Example Live Demodef pythagorean_triplets(limits) : c, m = 0, 2 while c < limits : for n in range(1, m) : a = m * m - n * n b = 2 * m * n c = m * m + n * n if c > limits : break ...
Read MorePython Program to Print Numbers in a Range (1,upper) Without Using any Loops
When it is required to print the numbers in a given range without using any loop, a method is defined, that keeps displays numbers from higher range by uniformly decrementing it by one after every print statement.Below is the demonstration of the same −Example Live Demodef print_nums(upper_num): if(upper_num>0): print_nums(upper_num-1) print(upper_num) upper_lim = 6 print("The upper limit is :") print(upper_lim) print("The numbers are :") print_nums(upper_lim)OutputThe upper limit is : 6 The numbers are : 1 2 3 4 5 6ExplanationA method named ‘print_nums’ is defined.It checks if the upper limit is greater than 0.If ...
Read MoreConvert Nested Tuple to Custom Key Dictionary in Python
When it is required to convert a nested tuple into a customized key dictionary, the list comprehension can be used.Below is the demonstration of the same −Example Live Demomy_tuple = ((6, 'Will', 13), (2, 'Mark', 15), (9, 'Rob', 12)) print("Thw tuple is : ") print(my_tuple) my_result = [{'key': sub[0], 'value': sub[1], 'id': sub[2]} for sub in my_tuple] print("The converted dictionary is : ") print(my_result)OutputThw tuple is : ((6, 'Will', 13), (2, 'Mark', 15), (9, 'Rob', 12)) The converted dictionary is : [{'key': 6, 'value': 'Will', 'id': 13}, {'key': 2, 'value': 'Mark', 'id': 15}, {'key': 9, 'value': 'Rob', ...
Read MoreFlatten tuple of List to tuple in Python
When it is required to flatten tuple of a list to tuple, a method is defined, that takes input as tuple.The tuple is iterated over, and the same method is called on it over and over again until the result is obtained.Below is the demonstration of the same −Example Live Demodef flatten_tuple(my_tuple): if isinstance(my_tuple, tuple) and len(my_tuple) == 2 and not isinstance(my_tuple[0], tuple): my_result = [my_tuple] return tuple(my_result) my_result = [] for sub in my_tuple: my_result += flatten_tuple(sub) return tuple(my_result) my_tuple = ((35, 46), ((67, ...
Read MorePython program to Order Tuples using external List
When it is required to order the tuples using an external list, the list comprehension, and ‘dict’ method can be used.Below is the demonstration of the same −Example Live Demomy_list = [('Mark', 34), ('Will', 91), ('Rob', 23)] print("The list of tuple is : ") print(my_list) ordered_list = ['Will', 'Mark', 'Rob'] print("The ordered list is :") print(ordered_list) temp = dict(my_list) my_result = [(key, temp[key]) for key in ordered_list] print("The ordered tuple list is : ") print(my_result)OutputThe list of tuple is : [('Mark', 34), ('Will', 91), ('Rob', 23)] The ordered list is : ['Will', 'Mark', 'Rob'] The ordered tuple list is ...
Read MoreRemove Tuples of Length K in Python
When it is required to remove the tuples of a specific length ‘K’, list comprehension can be used.Below is the demonstration of the same −Example Live Demomy_list = [(32, 51), (22, 13 ), (94, 65, 77), (70, ), (80, 61, 13, 17)] print("The list is : " ) print(my_list) K = 1 print("The value of K is ") print(K) my_result = [ele for ele in my_list if len(ele) != K] print("The filtered list is : ") print(my_result)OutputThe list is : [(32, 51), (22, 13), (94, 65, 77), (70, ), (80, 61, 13, 17)] The value of K is ...
Read MoreExtract digits from Tuple list Python
When it is required to extract digits from a list of tuple, list comprehension can be used.Below is the demonstration of the same −Example Live Demomy_list = [(67, 2), (34, 65), (212, 23), (17, 67), (18, )] print("The list is : ") print(my_list) N = 2 print("The value of N is ") print(N) my_result = [sub for sub in my_list if all(len(str(ele)) == N for ele in sub)] print("The extracted tuples are : " ) print(my_result)OutputThe list is : [(67, 2), (34, 65), (212, 23), (17, 67), (18, )] The value of N is 2 The extracted tuples ...
Read MoreJoin Tuples if similar initial element in Python
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 ...
Read MoreClosest Pair to Kth index element in Tuple using Python
When it is required to find the closest pair to the Kth index element in a tuple, the ‘enumerate’ method can be used along with ‘abs’ method.Below is the demonstration of the same −Example Live Demomy_list = [(5, 6), (66, 76), (21, 35), (90, 8), (9, 0)] print("The list is : ") print(my_list) my_tuple = (17, 23) print("The tuple is ") print(my_tuple) K = 2 print("The value of K has been initialized to ") print(K) min_diff, my_result = 999999999, None for idx, val in enumerate(my_list): diff = abs(my_tuple[K - 1] - val[K - 1]) if diff ...
Read MoreCreate a list of tuples from given list having number and its cube in each tuple using Python
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 ...
