#Pseudocode for sorting

#define a function to sort:
#    set the index as 0
#    set the new list as empty
#    for number in a list:
#         take the first number and insert it into the list
#         now take the second number in a list, and compare it to numbers in the new list
#         while the number is greater than the next number in the list:
#               insert into list


#the first item in the new list is the first item in the old list
#new_list = old_list[0]
#list of indexes range(len(old_list))
#compare each item

#Min_sorting, this is cheeky, but works nicely. Probably not fair to use min though
def min_sorting(lst):
    new_list = []
    for number in range(len(lst)):
        lowest_number = min(lst)
        new_list.append(lowest_number)
        lst.remove(lowest_number)
    return new_list
