Tkinter and after() method
by Phil Feb. 1, 2023

Feb. 1, 2023

It's been quite some time since I've played with Tkinter and despite searching the Internet for most of the day I seem to have hit a dead-end. I'm trying to put a pause within a for-loop as follows: def my_function(self): for i in range(5): do something here eg. print(i) self.after(1000) Instead of printing i every second my_function is delayed for 5 seconds. To try to get some understanding of what's required I tried this: self.r = 31 self.abc() self.print_count() self.after(1000, self.print_count() def abc(self): self.r += 1 print(self.r) def print_count(self) self.abc() self.after(1000, self.print_count() This prints 32 - 1025, without a one second delay, before the programme ends with: "RecursionError: maximum recursion depth exceeded while calling a Python object". Although I haven't tried it I suspect that if I used a label to display the count rather than a print statement then I might not see a recursion error. I probably should try that before posting this but I've got a splitting headache and it hasn't helped with my original delay within a for_loop problem. -- Regards, Phil

question about Scribe window
by Melinda Fatani Jan. 31, 2023

Jan. 31, 2023

I am working virtually with an elementary student trying to learn Python. We are following a interactive curriculum I found on Twinkle.com. Things are going well, but my student can't open a Scribe window. We made sure that we have the latest Python download, but there is no bar at the top of his IDLE window to open a Scribe window. Is there a way to do that, if it doesn't show the tool bar at the top? Melinda

Re my earlier question about after()

I found the answer to the second part of my question, instead of self.after(1000, self.print_count() it should be self.after(1000, self.print_count). So please ignore all after how do I insert a delay within a for_loop. -- Regards, Phil

Arrow keys in subwindows
by paulf＠quillandmouse.com Jan. 13, 2023

Jan. 13, 2023

Folks: I can't seem to get the arrow keys (KEY_LEFT, KEY_RIGHT) to work in subwindows. I'm running Debian Linux with version 3.10.9 of Python. When I run my code using stdscr, arrow keys work just fine. I do a a key = stdscr.getch(), it registers the keys. But when I use a subwindow (key = mysubwin.getch()), they don't register. No exception dumped, but the arrow keys just don't register. Has anyone else seen this behavior, and can you explain it? Paul -- Paul M.

Re: [Tutor] finding common words using set
by seraph Jan. 1, 2023

When I ran your code, it returned *banana. *You mentioned it should return "*banana and orange*." However, based on the example that you provided, it should only return *banana*. strings = ['apple orange banana', 'orange banana grape', 'banana mango'] > The common word in these 3 groups is *banana *- not *banana & orange*. I hope this helps! Seraph

finding common words using set.
by mhysnm1964＠gmail.com Jan. 1, 2023

Jan. 1, 2023

All, I have created a function to find the common words within a list of strings. I never get any results back of the common words and cannot understand why. This is the first time I have delt with the set data methods and are trying to understand how to use them. def find_common_words(strings): # Split the strings into lists of words word_lists = [s.split() for s in strings] # Find the intersection of the sets of words common_words = set(word_lists[0]).intersection(*word_lists[1:]) # Join the common words into a single string return ' '.join(common_words) strings = ['apple orange banana', 'orange banana grape', 'banana mango'] common_words = find_common_words(strings) print(common_words) Should return banana orange and I get a null string. Any ideas why? Sean
