python sort list of lists by specific index

# Basic syntax:
nested_list.sort(key = lambda nested_list: nested_list[1]) 

# Example usage:
nested_list = [['I', 4, 28], 
               ['O', 2, 20], 
               ['U', 1, 20], 
               ['A', 3, 21],
               ['FISH', 42, 23]]
nested_list.sort(key = lambda nested_list: nested_list[1]) 
print(nested_list)
--> [['U', 1, 20], ['O', 2, 20], ['A', 3, 21], ['I', 4, 28], ['FISH', 42, 23]]
# Note that the list of lists was sorted in place and that the nested
#	lists were all sorted by their first index (*Python is 0-indexed)
