Python program to find the minimum and maximum value in a list of tuples
tuple_list = [(6, 5), (3, 8), (1, 6), (4, 7), (3, 1)] ele1 = tuple(map(max, zip(*tuple_list))) ele2 = tuple(map(min, zip(*tuple_list))) print(ele1, el2) #Output: (6, 8) (1, 1)
- The built-in max() function returns the largest element in an iterable.
- The built-in min() function returns the smallest element in an iterable.
- The zip() built-in method returns an iterator of tuples, grouping the similar index of multiple sequences so that they can be used as a single entity.
- The ‘*’ operator unpacks every element of an iterable to other variables dynamically.
- The built-in map() function applies a given function to each element of an iterable and returns a list of the results.
- The tuple() built-in method takes an iterable and creates a new tuple of its elements.
Python program to get the minimum difference in Tuple pair
tuple_list = [(1, 7), (6, 9), (3, 10), (5, 3), (8, 4), (2, 7)] #using list comprehension diff_list = [abs(ele2 - ele1) for ele1, ele2 in tuple_list] diff1 = min(diff_list) print(diff1) #Output: 2
- List comprehension is a compact method that defines a list and its contents at the same time. Its basic syntax consists of a square bracket with an expression that is executed for each element along with for loop to iterate over each element.

- The built-in abs() function returns the absolute value of a number.
Python program to get the union of Tuples
tuple1 = (7, 6, 8) tuple2 = (4, 2, 6, 4, 8) #using + operator tuple3 = tuple(set(tuple1 + tuple2)) print(tuple3) #Output: (2, 4, 6, 7, 8) #using union() tuple4 = tuple(set(tuple1).union(set(tuple2))) print(tuple4) #Output: (2, 4, 6, 7, 8)
- The ‘+’ operator joins multiple tuples together.
- The set() built-in method creates a set of the iterable passed. A set in python represents a mathematical notion of a set and performs set operations like union, intersection, difference, etc. It is an unordered collection of immutable and unique elements in python.

Python program to perform AND operation between Tuples
tuple1 = (6, 2, 3) tuple2 = (1, 8, 2) and_tuple = tuple(map(lambda ele1, ele2: ele1 & ele2, tuple1, tuple2)) print(and_tuple) #Output: (0, 0, 2)
- The lambda function is a function that is defined without a name. It can have any number of arguments but only one expression as it is a small function having a single line of code. The expression is evaluated and returned.
- The & operator performs bitwise and operation between elements of the tuples having similar indexes. It returns 1 if both the bits are 1, otherwise, it returns 0.
Python program to perform XOR operation on tuples
tuple1 = (9, 6, 1) tuple2 = (4, 6, 8) XOR_tuple = tuple(ele1 ^ ele2 for ele1, ele2 in zip(tuple1, tuple2)) print(XOR_tuple) #Output: (13, 0, 9)
- The ^ operator performs the bitwise XOR operation between elements of the tuples having similar indexes. It returns 1 if one of the bits is 0 and the other bit is 1. If both the bits are 0 or 1, then it returns 0.
Python program to convert string tuples to list tuples
list_tup1 = ["('BetaPython:', 2)", "('Python', 10)", "('for', 9)", "('U', 8)"] #using list comprehension list_tup2 = [eval(ele) for ele in list_tup1] print(list_tup2) #Output: [('BetaPython:', 2), ('Python', 10), ('for', 9), ('U', 8)] #using map() list_tup3 = list(map(eval, list_tup1)) print(list_tup3) #Output: [('BetaPython:', 2), ('Python', 10), ('for', 9), ('U', 8)]
- The built-in eval() function evaluates the python string expression passed as an argument runs within the program and returns the result as an integer.
