While Loops

You havent declare variable m and total, before the loop

Oh sorry I typed in the wrong one

z = 2 sum = 0 while z<9: z += 1 sum=sum+z print (sum)

Whats wrong with that ?

Nothing is, I just don’t know how you get the output

Can you please explain it to me?

Try adding this line print(str(sum)+"+"+str(z)) Inside the loop :D

The answer is 42. I just wanna know how to get to it because I have this worksheet with a bunch of while loops problems but I don’t know how to do them without checking with python. Could you please show me the steps to it?

z = 2 sum = 0 while z<9: print("z:",z,"\nsum:",sum,"\nz+=1: ", z+1, "\nsum+z: ",sum+(z+1),"\n----\n") z += 1 sum=sum+z print (sum)

???? I don’t get it :/

Try to run the code, each step will be printed
