[Python] Python - Problem with sorting a list without using the sort() method

I'm a beginner in Python and I'm trying to create a function that sorts a list of integers without using the .sort() method. Here's what I wrote:

def mon_tri(liste):
for i in range(len(liste)):
for j in range(len(liste) - 1):
if liste[j] > liste[j + 1]:
liste[j], liste[j + 1] = liste[j + 1], liste[j]
return liste

print(mon_tri([5, 3, 1, 4, 2]))


I'm trying to create a function that sorts a list of integers without using the .sort()

But sometimes the results aren't sorted correctly. I don't understand why.

What's wrong with my logic? Is there a better way to do this without using .sort()?

Thanks in advance for your advice
