Python add numbers up in loop -

i have list of numbers:

list1 = [33, 11, 42, 53, 12, 67, 74, 34, 78, 10, 23]

what need calculate total amount of numbers in list, divide 360 work out portions of circle. example 32. have done below:

def heading():     heading_loop in range(len(list1)):         heading_deg = (360 / len(list1))     return heading_deg 

the problem have need have number (heading_deg) append last number everytime runs throught loop. e.g.

run 1:  32 run 2:  64 run 3:  96 run 4:  128 

etc etc

any ideas?? @ moment return 32, 11 times.

thanks!!

i'm sorry i've posted answer think wanna different show in code. have if want:

def heading():     result=[] #create void list     numbersum=sum(list1) #"calculate total amount of numbers in list" # e.g. if list=[1,1,2] sum(list) return 1+1+2.      in range(len(list1)):          result.append(((list1[i])/float(numbersum))*360) # calculate portion of circle ("then divide 360 work out portions of circle")  #in case if have list a=[250,250] function return 2 angle of 180°      #however can return portion of circle in percent e.g. 0.50 half circle 1 whole circle removing "*360" code above      return result 

if try:

 test=heading()  print test  print sum(test) 

the last should print 360°.
