Advent of Code 2020: Python Solution Day 6

Advent of Code 2020: Python Solution (25 Part Series)

I am trying this only after few hour of the challenge unlocked. And first part was easy to solve. But for second part, I had to take help from reddit thread, specially here.
From few challenges, I first started with the toy example given there and if all the cases matches on this example input then feed my input to this algorithm and done. Here, day6_test.txt is a example input present on the challenge link. And day6.txt is my input. A repo with output is present at GitHub.

with open("day6_test.txt", "r") as fp:
    lines=fp.readlines()

with open("day6.txt", "r") as fp:
    lines=fp.readlines()

groups = []
group = []
for question in lines:
    if question!="\n":
        group.append(question.split("\n")[0])
    else:
        groups.append(group)
        group=[]
groups.append(group)

# solution to challenge 1 solution_1 = []
for group in groups:
    #print(f"Group: ", group)     unique_ques = []
    for ques in group:
        unique_ques.extend([uq for uq in ques])

    #print(f"Unique questions: {set(unique_ques)}")     solution_1.extend(list(set(unique_ques)))
print(f"Solution 1: {len(solution_1)}")


# solution to challenge 2 from collections import Counter
total = 0
for group in groups:
    #print(f"\nGroup: {group}")     group_size = len(group)
    #print(f"Length of group: {group_size}") 
    # make single list of enitire group and count occurence     counts = Counter("".join(group))
    #print(counts) 
    counts = Counter(list(counts.values()))[group_size]
    total+=counts
print(f"Solution 2:", total)

I write blogs about Computer Vision projects on my GitHub page q-viper.github.io and if you got some time please share yours too.
