Python- Finding average -


i trying find average number of times user guesses number. user asked how many problems want , program give them many problems. having trouble recording amount of times guess , wrong , guess , right , finding average between two. have far

print("hello!") random import randint  def hooblah():     randoma = randint(0,12)     randomb = randint(0,12)     answer = 0     correctanswer = (randoma*randomb)     realanswer = (randoma*randomb)     avgcounter = 0     avgcorrect = 0     average = 0     print("what {0} * {1} ?".format(randoma,randomb))     while answer != realanswer:         = input("what's answer? ")         answer = int(an)         if answer == correctanswer:             avgcorrect+=1             print("correct!")             average+=((avgcorrect+avgcounter)/avgcorrect)         else:             avgcounter+=1             if answer > correctanswer:                 print("too high!")             else:                 print("too low!")   def main():     numproblems = input("how many problems solve? ")     problems = int(numproblems)     if problems in range(1,11):         problems in range(problems):             hooblah()         else:              print("average number of tries: {0}".format(hooblah,average))      else:         print("please input value between 1 through 10!") main()

thanks!

so tried change little possible not cramp style. think this, average number of guesses needed correct answer total number of guesses divided number of correct guesses. because make sure user gets correct answer, number of correct guesses number of problems!

so each time run hooblah(), return number of guesses took correct answer. add outside loop, @ end of loop, divide number of guesses number of problems , you've got answer! also, don't think python supports '+=', may need change avgcounter+=1 avgcounter = avgcounter +1, totally may mistaken, switch between languages bunch!

one note cast numguesses float ( float(numguesses) ), make sure int data type doesn't truncate average. example, wouldn't want 5/2 come out 2, want 2.5, float!

hopefully helps! 

from random import randint  def hooblah():     randoma = randint(0,12)     randomb = randint(0,12)     answer = 0     correctanswer = (randoma*randomb)     realanswer = (randoma*randomb)     avgcounter = 0     average = 0     print("what {0} * {1} ?".format(randoma,randomb))     while answer != realanswer:         = input("what's answer? ")         answer = int(an)         if answer == correctanswer:             print("correct!")             return avgcounter         else:             avgcounter+=1             if answer > correctanswer:                 print("too high!")             else:                 print("too low!")   def main():     problemsstring = input("how many problems solve? ")     numproblems = int(problemsstring)     numguesses = 0     if numproblems in range(1,11):         problem in range(numproblems):             numguesses = numguesses + hooblah()         print("average number of tries: " + str(float(numguesses)/numproblems)      else:         print("please input value between 1 through 10!") main()

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
