[Python] Nested list hacker rank quetion [closed]

My program in hacker rank keeps on giving me IndexError: list index out of range for second_score = sorted(set([item[1] for item in nested_list]))[1] where as it runs perfectly for visula code.

nested_list.sort(key= lambda x:[x[1],x[0]])
second_score = sorted(set([item[1] for item in nested_list]))[1]

list.sort()
for j in list:
print(j)
