How to sort Numbers in Python without sort function examples

A simple example code sorts the given list in ascending order using a while loop. Use the append method and remove method to update the list.

my_list = [4, 2, 3, -1, -2, 0, 1]
new_list = []

while my_list:
    min = my_list[0]
    for x in my_list:
        if x < min:
            min = x
    new_list.append(min)
    my_list.remove(min)

print(new_list)

Output:

Another example with for-loop and range function

my_list = [4, 2, 3, -1, -2, 0, 1]

for i in range(len(my_list)):
    for j in range(i + 1, len(my_list)):

        if my_list[i] > my_list[j]:
            my_list[i], my_list[j] = my_list[j], my_list[i]

print(my_list)

Output: [-2, -1, 0, 1, 2, 3, 4]
