How do I get the sum of all numbers in a range function in Python? -

-

i can't figure out how take x (from code below) , add sum , divide number of ratings. example given in class 4 ratings, numbers being 3,4,1,and 2. average rating should 2.5, can't seem right!

number_of_ratings = eval(input("enter number of difficulty ratings positive integer: "))       # number of difficulty ratings in range(number_of_ratings):      #   each diffuculty rating     x = eval(input("enter difficulty rating positive integer: "))      # next difficulty rating average = x/number_of_ratings print("the average diffuculty rating is: ", average)

your code doesn't add anything, overwrites x in each iteration. adding variable can done += operator. also, don't use eval:

number_of_ratings = int(input("enter number of difficulty ratings positive integer: ")) x = 0 in range(number_of_ratings):     x += int(input("enter difficulty rating positive integer: ")) average = x/number_of_ratings print("the average diffuculty rating is: ", average)

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
