Get difference between two lists

Question

I have two lists in Python, like these: temp1 = ['One', 'Two', 'Three', 'Four'] temp2 = ['One', 'Two'] I need to create a third list with items from the first list which aren't present in the second one. From the example I have to get: temp3 = ['Three', 'Four'] Are there any fast ways without cycles and checking? Select the correct answer from above options

Answer 1

There are many ways of getting unique values from the above two lists some of them are as follows:- The first thing we can do is use list comprehension. s = set(temp2) temp3 = [x for x in temp1 if x not in s] Full code of this is:- temp1 = ['One', 'Two', 'Three', 'Four'] temp2 = ['One', 'Two'] s = set(temp2) temp3 = [x for x in temp1 if x not in s] print(temp3) Another way we can solve the above problem by using list(set(temp1) - set(temp2)) method. Code of this is:- temp1 = ['One', 'Two', 'Three', 'Four'] temp2 = ['One', 'Two'] temp3=list(set(temp1) - set(temp2)) print(temp3)
