Given a list of binary tuples, the task is to write a Python program to remove all tuples that are duplicates irrespective of order, i.e delete if contains similar elements, irrespective of order.

Input :test_list = [(4, 6), (1, 2), (9, 2), (2, 1), (5, 7), (6, 4), (9, 2)]

Output :[(1, 2), (5, 7), (4, 6), (2, 9)]

Explanation :(2, 1), (6, 4) are removed as (1, 2), (4, 6) are already included.

Input :test_list = [(4, 7), (1, 2), (9, 2), (2, 1), (5, 7), (7, 4), (9, 2)]

Output :[(1, 2), (5, 7), (4, 7), (2, 9)]

Explanation :(2, 1), (7, 4) are removed as (1, 2), (4, 7) are already included.

**Method 1 : ***Using **map()**, **sorted()**, **set()** and **list()*

In this, we sort each element of tuple using sorted() and map(). Then result is converted to set to remove duplicates. At last, set is converted to list.

**Example:**

## Python3

`# initializing list` `test_list ` `=` `[(` `4` `, ` `6` `), (` `1` `, ` `2` `), (` `9` `, ` `2` `), (` `2` `, ` `1` `), (` `5` `, ` `7` `), (` `6` `, ` `4` `), (` `9` `, ` `2` `)]` ` ` `# printing original list` `print` `(` `"The original list is : "` `+` `str` `(test_list))` ` ` `# using map() to get all sorted` `# set removes duplicates` `res ` `=` `list` `({` `*` `map` `(` `tuple` `, ` `map` `(` `sorted` `, test_list))})` ` ` `# printing result` `print` `(` `"Tuples after removal : "` `+` `str` `(res))` |

**Output:**

The original list is : [(4, 6), (1, 2), (9, 2), (2, 1), (5, 7), (6, 4), (9, 2)]

Tuples after removal : [(2, 9), (1, 2), (4, 6), (5, 7)]

**Method 2 : ***Using** list comprehension,** **sorted()** and **set()*

This is a naive approach for the required solution. In this, each element of list is sorted using list comprehension and sorted(), then result is converted back to remove duplicates using set().

**Example:**

## Python3

`# initializing list` `test_list ` `=` `[(` `4` `, ` `6` `), (` `1` `, ` `2` `), (` `9` `, ` `2` `), (` `2` `, ` `1` `), (` `5` `, ` `7` `), (` `6` `, ` `4` `), (` `9` `, ` `2` `)]` ` ` `# printing original list` `print` `(` `"The original list is : "` `+` `str` `(test_list))` ` ` `# sorting tuples` `temp ` `=` `[` `tuple` `(` `sorted` `(sub)) ` `for` `sub ` `in` `test_list]` ` ` `# removing duplicates` `res ` `=` `list` `(` `set` `(temp))` ` ` `# printing result` `print` `(` `"Tuples after removal : "` `+` `str` `(res))` |

**Output:**

The original list is : [(4, 6), (1, 2), (9, 2), (2, 1), (5, 7), (6, 4), (9, 2)]

Tuples after removal : [(2, 9), (1, 2), (4, 6), (5, 7)]
