Just cant seem to figure this out..... python

"Write a program which repeatedly reads numbers until the user enters “done”. Once “done” is entered, print out the total, count" I understand the question and can write it out in English but no matter what I try I can't get it to do it. I have started all over so many times now. the chapter ( self-taught) does not give enough info to do this. please help... dont mind the "#" that is just some different attempts n = 0 while True: user = input('Enter Numbers:') #if n != 0: #n = n + float(user) if user == 'done': user = n n = n + float(user) total = sum(n) print(total) print('Total:', total) break

n=0 user = input("enter numbers") while user != "done": n+=float(user) user = input("enter numbers") print(n)

The logic of the code I guess. having trouble making sense of what is actually happening.. I'm a math person ( a physicist) and the logic is killing me I am just trial and error where to put stuff lol.. this is the full question and where I am at now... I got it to work so far .. but the try except is spitting out a infinite loop now.. a "continue" and "break" probably needs to go somewhere... I think "Write a program which repeatedly reads numbers until the user enters “done”. Once “done” is entered, print out the total, count, and average of the numbers. If the user enters anything other than a number, detect their mistake using try and except and print an error message and skip to the next number." n = 0 count = 0 user = input('Enter Numbers:\n> ') while user != 'done': try: count = count + 1 n = n + float(user) user = input('> ') avg = n/count if user == 'done': print('Total',n) print('Count:',count) print('Average:',avg) except: print('Please Enter or "done"')

Your logic is correct and your program works like you said but in Code Playground SoloLearn is different because only it only will show you 1 input so if you write for example with new línea (enter) 5 6 9 done you must to see a result, finishing inifinity while. Total: 30 Count: 3 Average: 10

Sorry I am not sure what you mean? I am not using the sololearn playground. Just trying to get the try/except to work now. and my logic is just guessing and trial and error not even sure what I did lol...

Ahh ok, I think I understand you now. Well you can check that http://www.pythonforbeginners.com/error-handling/exception-handling-in-JUMP_LINK__&&__python__&&__JUMP_LINK to try to understand except better

right.. I have used the try/except before but the question is asking me to skip to the next number which I cant get to work.. just keeps making an infinite loops for some reason... "If the user enters anything other than a number, detect their mistake using try and except and print an error message and skip to the next number."

ok............. now I am at a loss... I got the try/except in the right spot so it at least skips to next number... however now the count is wrong. the average is including the string Code n = 0 count = 0 user = input('Enter Numbers:\n> ') while user != 'done': count = count + 1 try: n = n + float(user) except: print('Enter Numbers or "done"') user = input('> ') avg = n/count if user == 'done': print('Total',n) print('Count:',count) print('Average:',avg) output Enter Numbers: > 4 > 5 > bad Enter Numbers or "done" > 7 > done Total 16.0 Count: 4 Average: 4.0 Process finished with exit code 0 the average is doing ( 4 + 5 + "bad" + 7)/4 when it should not include bad...

Maybe is better to use if statement only to run each instruction per each case

Change try and except only for If, else if, else

Share your code from your playground if you need help

yeah... only place it works is around the n variable but then the average is wrong becasue of the count.. I just tried the try/except around the if statement and it failed. n = 0 count = 0 user = input('Enter Numbers:\n> ') while user != 'done': try: n = n + float(user) except: print('Enter Numbers or "done"') user = input('> ') count = count + 1 # if user != 'done' or user != n: #count = count avg = n/count if user == 'done': print('Total:',n) print('Count:',count) print('Average:',avg)

You can try using repl.it to run python programs
