Compare Two Lists Python Python Guides How to compare two lists in python using sort () method. the sort () method of python sorts the list, and it sorts the original list. here, when the list is sorted, all the items same items in the list will have the same index position. then, using the == operator, you can compare two lists. for example, look at the code below for how two lists. To find the unmatched values from the lists, we have to convert our list to the set datatype, and then only you can use the difference () method. syntax. set1.difference(set2) set1.difference (set2): it will return the values included in set1 but not in set2. let’s understand how we can compare two lists and get the difference between two.
How To Compare Two Lists In Python Python Guides # short list: compare bitwise took 10.145 ms compare listcomp took 11.157 ms compare intersect took 7.461 ms # long list: compare bitwise took 11203.709 ms compare listcomp took 17361.736 ms compare intersect took 6833.768 ms. Compare if 2 lists are equal regardless of order. sort lists and compare; compare individual elements; get intersection of 2 lists; get difference of 2 lists; compare if 2 lists are equal ignoring case; compare if 2 lists are equal with same order. to compare something in python, we use == operator or is operator. This approach simply uses the == operator to compare 2 lists element wise and returns true if they have the same length and the same elements in the same order and false otherwise. it also works for any type of element, even if they are not hashable or mutable. example: list a = ['a', 'b', 'c', [1, 2, 3], {'sling': 'academy'}] list b = ['a', 'b. Lists of different lengths are never equal. this article describes how to use the following python features to compare lists: sort () method or the sorted () function with the == operator. set () function with the == operator. reduce () and map () functions with the == operator. collection.counter () class with the == operator.

Method 4: using the difflib module. the difflib module in python is a tool mainly designed for comparing sequences, including lists. it is particularly useful when you are not only interested in the items present in the lists but also in the differences character by character. here’s an example: import difflib. List comprehension is a concise and powerful way to compare two lists in python. it allows you to create a new list by iterating over existing lists and applying certain conditions. here’s an example of using list comprehension to compare lists: l1 = [10, 20, 30, 40, 50] l2 = [50, 75, 30, 20, 40] l3 = [50, 20, 30, 40, 10].
