python sort a list by a custom order
# Example usage: list_to_sort = [('U', 23), ('R', 42), ('L', 17, 'D')] custom_sort_order = ['R', 'D', 'L', 'U'] sorted(list_to_sort, key=lambda list_to_sort: custom_sort_order.index(list_to_sort[0])) # Where 0 is the tuple index to use for sorting by custom order --> [('R', 42), ('L', 17, 'D'), ('U', 23)]
