if min is not

[tplace]

Hello,
I start in python and I don't understand the line (if min is not en_cours :) in this sorting by insertion program:

A = [8,6,15,9,2,1,99,5,7]
print (A)
nb = len(A)
for en_cours in range(0,nb):
    plus_petit = en_cours
    for j in range(en_cours+1,nb) :
        if A[j] < A[plus_petit] : 
           plus_petit = j
    if min is not en_cours :
        print (min)
        temp = A[en_cours]
        A[en_cours] = A[plus_petit]
        A[plus_petit] = temp
print(A)  

thank for your help Thierry

there are multiple issues in this code.
min is built-in function, that is why this code doesn't produce an error. You should not use built-in functions as names.
then you need to define whatever min is supposed to be (i.e. instead of min use some other name and define that name in advance). Let say you replace min with num.
it looks like you wanted to test for inequality, not for identity. is is checking for identity (i.e. both are same object with same id), == checks for eqaulity (same value, not necessary same object), != checks for inequality`
you should use if num != en_course:

If the result will be what you expect - make the changes and see
