Simple for loop question

mysum=0 for i in range(5,11,2) mysum +=i if mysum==5: break mysum +=1 print(mysum) In line 3, when I remove = operator , the result would be zero Why we need to add '=' ?

Because mysum+=i is equivelent to mysum=mysum+i.. so if u do not assign mysum+i value to mysum variable..the result would show you zero.. did u understand????

if we don't add '=' , we cannot add mysum to i That the area I am confusing

I just found the answer.thank you!! If I have a '/' instead of '+', the left side element would be divided by right side element. That mean when I have a single element on left-hand side, I replace that single element with whatever's on the right-hand side

not only / operator but will work * , - n % too.. = operator assigns value so if u write mysum+i there will b no logic ..we want there = to assign the calculation to mysum variable..
