68,992,767 | I'm trying to implement selection sort in python using a list. But the implementation part is correct and is as per my algorithm but it is not resulting in correct output. Adding my code:

my_list = [64, 25, 12, 11, 32]
def selection_sort(element_list):
for element in range(len(element_list)):

for element in range(len(element_list)):
mindex = element
for compare_index in range(element+1, len(element_list)):
if element_list[mindex] > element_list[compare_index]:
mindex = compare_index
... | Your algorithm is almost correct but
`element_list[compare_index], element_list[mindex] = element_list[mindex], element_list[compare_index]` in this line you made the mistake.
It shouldn't be `compare_index`, it should be `element`. Please check the correct algorithm below
