input: Write a function to create a lambda expression in Python to filter a list of integers greater than 50. The function should return the filtered list.
  
  assert list(filter_greater_than_50([45, 12, 52, 89, 33, 99])) == [52, 89, 99]
  assert list(filter_greater_than_50([10, 20, 30, 40, 50, 60])) == [60]
  assert list(filter_greater_than_50([55, 56, 57, 58, 59])) == [55, 56, 57, 58, 59]
  assert list(filter_greater_than_50([35, 45, 55, 65, 75, 85])) == [55, 65, 75, 85]
  assert list(filter_greater_than_50([])) == []
output: def filter_greater_than_50(lst):
      return list(filter(lambda x: x > 50, lst))
