If you want to get only one student:

student_details = [['john', 20], ['jack', 10], ['tom', 15]]
student_detail_with_min_score = min(student_details, key=lambda detail: detail[1])
print(student_detail_with_min_score)
print(student_detail_with_min_score[0])
print(student_detail_with_min_score[1])

Output:

['jack', 10]
jack
10

min function finds the minimum of student_details, but it will use student_details[i][1] as the key while comparing.

Read the official documentation to understand how the min function works with the key argument.

If you want to get all the students with the minimum score:

student_details = [['rock', 10], ['john', 20], ['jack', 10], ['tom', 15]]

min_score = min(student_details, key=lambda detail: detail[1])[1]

student_details_with_min_score = [
    student_detail for student_detail in student_details if student_detail[1] == min_score
]

print(student_details_with_min_score)

Output:

[['rock', 10], ['jack', 10]]
