Python | Check if two list of tuples are identical
• Last Updated : 11 Nov, 2019

Sometimes, while working with tuples, we can have a problem in which we have list of tuples and we need to test if they are exactly identical. This is a very basic problem and can occur in any domain. Let’s discuss certain ways in which this task can be done.

Method #1 : Using` == `operator
This is the simplest and elegant way to perform this task. It also checks for equality of tuple indices with one other.

 `# Python3 code to demonstrate working of``# Check if two list of tuples are identical``# using == operator`` ` `# initialize list of tuples ``test_list1 ``=` `[(``10``, ``4``), (``2``, ``5``)]``test_list2 ``=` `[(``10``, ``4``), (``2``, ``5``)]`` ` `# printing original tuples lists``print``(``"The original list 1 : "` `+` `str``(test_list1))``print``(``"The original list 2 : "` `+` `str``(test_list2))`` ` `# Check if two list of tuples are identical``# using == operator``res ``=` `test_list1 ``=``=` `test_list2`` ` `# printing result``print``(``"Are tuple lists identical ? : "` `+` `str``(res))`
Output :
```The original list 1 : [(10, 4), (2, 5)]
The original list 2 : [(10, 4), (2, 5)]
Are tuple lists identical ? : True
```

Method #2 : Using `cmp()`
This inbuilt function, computes the difference of values of tuples. If they are computed out to be 0, then it means that tuples are identical. Works only with Python2.

 `# Python code to demonstrate working of``# Check if two list of tuples are identical``# using cmp()`` ` `# initialize list of tuples ``test_list1 ``=` `[(``10``, ``4``), (``2``, ``5``)]``test_list2 ``=` `[(``10``, ``4``), (``2``, ``5``)]`` ` `# printing original tuples lists``print``(``"The original list 1 : "` `+` `str``(test_list1))``print``(``"The original list 2 : "` `+` `str``(test_list2))`` ` `# Check if two list of tuples are identical``# using cmp()``res ``=` `not` `cmp``(test_list1, test_list2)`` ` `# printing result``print``(``"Are tuple lists identical ? : "` `+` `str``(res))`
Output :
```The original list 1 : [(10, 4), (2, 5)]
The original list 2 : [(10, 4), (2, 5)]
Are tuple lists identical ? : True
```
