How to make two different list of strings same?-CodePudding

I have two random lists of strings. The length of two lists won't be necessarily equal all the time. There is no repetition of the elements within a list.

list1=['A', 'A-B', 'B', 'C']
list2=['A', 'A-B', 'B', 'D']

I want to compare the two lists, and the final output should be two lists with all common elements.

Expected output:

list1_final=['A', 'A-B', 'B', 'C','D']
list2_final=['A', 'A-B', 'B','C', 'D']

How can I achieve this with a minimum number of lines of code?

CodePudding user response：

Use the set python module. Just using set1.intersection(set2) you can have the common elements between set1 and set2

CodePudding user response：

Youve requested 2 lists with all common elements:

list1=['A', 'A-B', 'B', 'C']
list2=['A', 'A-B', 'B', 'D']

list1_final=[]
list2_final=[]

for item in list1:
    if item in list2:
        list1_final.append(item)
        list2_final.append(item)

returns

list 1 = ['A', 'A-B', 'B'] list 2 = ['A', 'A-B', 'B']

Now your output doesnt match the question asked, do you want all items in both lists? not just the common ones?
