Different Indentation Different Result

[el_bueno]

sump=0
for num in listp:
    if num%2==0:
        sump=sump+num
        print(sump

sump=0
for num in listp:
    if num%2==0:
        sump=sump+num
    print(sump)

sump=0
for num in listp:
    if num%2==0:
        sump=sump+num
print(sump)

Here are technically the same code, but as I play around with the indentation of print(sump) Im having differente results.

Could someone explain to me why is it about the indentation of print that makes the result different every time?
