This is not bubble sorting, but selective sorting. Bubble sorting should be written as follows:

k=

For I in the range (len (k)-1):

For j(len(k)- 1-I) in the range:

If k [j] >; k[j+ 1]:

k[j]，k[j+ 1]=k[j+ 1]，k[j]

Print (k)

If you want to sort by selection, you can change it to:

k=

For I in the range (len (k)-1):

For j(I+ 1, len(k)) in the range:

If k [I] >; k[j]:

k[i]，k[j]=k[j]，k[i]

Print (k)
