How to do the break??

[fullmoon84]

i doing a proram where i will first ask the user to key in the datas they have, Lets 3, then i will on ly allow them to key in 3 datas.

after that , ithe 3 datas will be add together, giving the total sum automatically.

This is the program that i write:

total=0
aCounter=0
a=raw_input("insert a:\t")
a=float(a)
while a!=-1:
total=total+a
aCounter=aCounter+1
a=raw_input("insert a:\t")
a=float(a)
if aCounter!=0:
add=float(total)/aCounter
n=float(n)/aCounter
print"total X ia",add
if a==n:
break

but when i run , ii state there " break outside loop",. Can anyone tell me how to do?? thank you.

The actual program is tabbed, isn't it? Could you do that, I can't really tell whats going on otherwise. >.>


Well, I don't know. I might still not be able to tell what's going on, but it will help.

In future, please read guidlines so your posts look like this:

total=0
aCounter=0
nDataPoints = int(raw_input("How many data points?:\t"))
 
while 1:
    aCounter = aCounter + 1
    a = float(raw_input("insert data point:\t"))
    total = total + a
    if aCounter == nDataPoints:
        break
average = total/aCounter
print "Total = %f, Average = %f:" %(total, average)
 

Otherwise, nobody can see the structure of you code.

I think that the break command is not working because it is placed inside an if statement, whereas it should be placed in a loop.

I think that the break command is not working because it is placed inside an if statement, whereas it should be placed in a loop.

A better way to do that is:

for i in range(nDataPoints):
    a = float(raw_input("insert data point:\t"))
    total = total + a
 

you can use i which counts for zero to nDataPoints - 1 inside you loop if you need to.
