Re: [Tutor] Simple guessing game - need help with the math
I am a newbie (please correct me if I am wrong), but I happen to think
that it would be best to suggest that your input be in the same case
as that of your variables. In other words, it appears that you are
suggesting the user make an input choice of H, L, or C while the
program appears to want to handle the variables h, l, or c.
Clearly my statements do not directly relate to math, but I do not see
how your program would be able to handle the input of H, L, or C.

[Tutor] Printing a list count - Help
Hi everybody, I have a list that I want to go through and finally print a total count of particular items. In this case, I want to print the result of how many A's and B's are in the list. honor_roll_count = 0 student_grades = ["A", "C", "B", "B", "C", "A", "F", "B", "B", "B", "C", "A"] for grades in student_grades: honor_roll_count = honor_roll_count + 1 if grades == "A" or grades == "B": print honor_roll_count The above code prints 8 lines, each being an entry for which item in the list was either A or B. Again, I'm looking for the result to be the number 8 itself - the total number of instances that A or B occurs in the list. I'm sure there are a handful of easy solutions for this, I just haven't hit the right combo yet and I thought I'd reach out to the tutor list for a bit of advice. Please and thank you! ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Printing a list count - Help
honor_roll_count = 0 student_grades = ["A", "C", "B", "B", "C", "A", "F", "B", "B", "B", "C", "A"] for grades in student_grades: if grades == "A" or grades == "B": honor_roll_count = honor_roll_count + 1 print honor_roll_count That works more to my liking. Thanks a million, Danny and Bob!

Alex,
Thanks for taking this one step further! I do appreciate it... +1

Re: [Tutor] Good Text Editor/IDE for Python
Juan, Besides Kwrite, I actually use the tools that the others mentioned so far, although I don't use Emacs often at all (perhaps I have just not found an advantageous use for it yet). So no real added info here, but I will say that I've not personally ran into any problems with Sublime. For Windows, if you must continue to use it, I can venture to suggest you give Notepad++ a whirl for a text editor. I have used it on a handful of occasions and it _generally_ seemed okay enough to keep it in mind for a rainy day, such as right now. As for PyCharm, I have 0 experience with that so I can't offer any suggestions.
