Test if Tuple contains K in Python
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 MoreFind the Maximum of Similar Indices in two list of Tuples in Python
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 −Examplemy_list_1 = [( 67, 45), (34, ...
Read MoreFind minimum k records from tuple list in Python
When it is required to find the minimum 'k' records from a list of tuples, it can be done using the 'sorted' method and lambda function.The 'sorted' method is used to sort the elements of a list. 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.A list can be used to store heterogeneous values (i.e data ...
Read MoreGet maximum of Nth column from tuple list in Python
When it is required to get the maximum of 'N'th column from a list of tuples, it can be done using list comprehension and 'max' method.The list comprehension is a shorthand to iterate through the list and perform operations on it. The 'max' method returns the maximum of values among an iterable.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 −Examplemy_list = [( 67, 78, 39), (34, 23, 52), (99, ...
Read MoreGet minimum difference in Tuple pair in Python
When it is required to get the minimum different in a tuple pair from a list of tuples, it can be done using the 'min' method and the list comprehension.The list comprehension is a shorthand to iterate through the list and perform operations on it. The 'min' method returns the minimum of values among an iterable.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 −Examplemy_list = [( 67, 78), (39, ...
Read MoreRaise elements of tuple as power to another tuple in Python
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 −Examplemy_tuple_1 = ( 7, 8, 3, 4, 3, 2) my_tuple_2 = (9, 6, ...
Read MoreTuple XOR operation in Python
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 −Examplemy_tuple_1 = ( 7, 8, 3, 4, 3, 2) my_tuple_2 = (9, 6, 8, 2, 1, ...
Read MoreHow to convert list to dictionary in Python?
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 listExampledef 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, 'Bangalore', ...

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.

Read MoreN element incremental tuples in Python
When it is required to create 'N' element incremental tuples, generator expression and 'tuple' method can be used.Below is a demonstration of the same −ExampleN = 3 print("The value of 'N' has been initialized") print("The number of times it has to be repeated is : ") print(N) my_result = tuple((elem, ) * N for elem in range(1, 6)) print("The tuple sequence is : ") print(my_result)OutputThe value of 'N' has been initialized The number of times it has to be repeated is : 3 The tuple sequence is : ((1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, ...
