Question

Doing GCSE computing and as a homework task I need to do the below  I m only starting out with programming and I ve been trying to figure out how to do it but to no avail  I believe I need to use a function but searching  python function list  etc gives me no help when I try it   Can you just tell me how to   Ask user to input a  list of numbers  Print these numbers out for confirmation Convert them to a variable s   Add them together Divide sum by number of numbers entered - Not even the slightest clue as to how do that  Finally  print Average is and the result   What I ve got at current   print  Welcome  this program will find the average of a list of numbers you enter     numbers   input  Enter your numbers  seperated by spaces     print  You have entered    print numbers   print numbers 0   print numbers 1   print numbers 2   print numbers 3   print numbers 4   print numbers 5   print numbers 6    print len numbers    print  The average of the above numbers is      FURTHEST I VE GOT

The input   function returns a string which may contain a  list of numbers    You should have understood that the numbers 2  operation returns the third element of an iterable   A string is an iterable  but an iterable of characters  which isn t what you want - you want to average the numbers in the input string   So there are two things you have to do before you can get to the averaging shown by garyprice    convert the input string into something containing just the number strings  you don t want the spaces between the numbers  convert each number string into an integer   Hint for step 1  you have to split the input string into non-space substrings   Step 2  convert string to integer  should be easy to find with google   HTH

You want to iterate through the list  sum all the numbers  and then divide the sum by the number of elements in the list  You can use a for loop to accomplish this   average   0 sum   0     for n in numbers      sum   sum   n average   sum   len numbers    The for loop looks at each element in the list  and then adds it to the current sum  You then divide by the length of the list  or the number of elements in the list  to find the average   I would recommend googling a python reference to find out how to use common programming concepts like loops and conditionals so that you feel comfortable when starting out  There are lots of great resources online that you could look up    Good luck

You can use python s built-in function sum   sum will return the sum of all the values len to get list s length   code     gt  gt  gt  list    1 2 3 4   gt  gt  gt  sum list   gt  gt  gt  10  gt  gt  gt  len list   gt  gt  gt  4  gt  gt  gt  avg   float sum list   len list   gt  gt  gt  2 5  gt  gt  gt    In pyton3 don t want to specify float     gt  gt  gt  10   4  gt  gt  gt  2 5    Use float because when using python 2 x  because    int int returns int value  i e  2  float int returns float value  i e  2 5    While in Python 3 x    int int return float int  int return int
