I understand that my title was a little misleading, and I apologise for the

Don't use input(). Use raw_input() instead.
You almost never want input() in python 2.
name = raw_input()
score = float(raw_input())
marks.append([name, score])
marks = sorted(marks, key=lambda score:score[1])
lowest = marks[0][1]
marks = [ x for x in marks if x[1] != lowest]
This creates a brand new list. It eventually overwrites
the original marks list with the new list. But it never
modifies the original marks, it reassigns the new list
to the old variable.
second_lowest = marks[0][1]
lowest = sorted([x for x in marks if x[1]==second_lowest])
for row in lowest:
print row[0]
And it worked because I was using list comprehensions for removing the
element from the list. It didn't worked in the for loop before. I wanted to
ask why it didn't worked in for loop but worked in list comprehension.
Because the comprehension creates a new list from the old.
You were modifying the original list as you traversed it,
thus breaking your own for loop.
