How do you prevent spyder IDE from automatically closing the window after executing a program?
Windows 7
Anaconda 2.7 package.
I don't have this issue with geany. I'm sure I need some sort of command in the compiling options but I've googled for a couple hours and haven't found anything about this extremely EXTREMELY simple problem.
My test code:
for i in range(10):
print(1)
I want to see all of the 1s sitting there in front of me until I click close.

I am learning Python (v 3.7) on a Mac using PyCharm. As I practice using the turtle library, the program runs without error, outputs the correct graphics, but then the graphics screen disappears immediately after the code completes runnning. Adding time.sleep(5) at the end of my program persists it and also shows that the focus changed from PyCharm to a Python program menu (which I can't find or turn on in the hope of keeping running).
When I use Thonny, the output persists, so I can check my work. How can I make it persist in PyCharm?
A well-structured Python turtle program will end with a call to mainloop() or one of its variants (exitonclick(), done()) This turns control over to the underlying tkinter event handler which will keep your window open, awaiting user events. Without this, the program simply ends and the window closes.
You don't need time.sleep() nor input("Press Enter to continue..."). Some Python programming environments clash with mainloop() but even those tend to disable it behind the scenes so the same code works everywhere.
First, do not use PyCharm to test. If you like it, more power to you, but personally, I have had many issues with output and PyCharm. Learn the command line, since you are using Mac. CodeAcacdemy and LinuxJournery have really good resources on that subject. Second, if you are still having issues, please reinstall trutle, Python 3.7 (there were some issues wiht it displaying on Mac), and macOS itself. Have a great day!

Problems getting pygame to show anything but a blank screen on Macos Mojave
For some reason, whenever I try to open a python script that has around ~450 lines of code, IDLE's windows simply appears empty and when I try to run it doesn't run anything either... However, if I try to run a smaller program it works for some reason. Does anybody know how I am able to run a python script on my Mac besides IDLE or how to fix the IDLE window being blank whenever I open a file?
To learn how to run Python Python programs on a Mac, read Chapters 1 and 4 of Python Setup and Usage. Running from an IDLE editor is just one way.
IDLE uses the tkinter module which wraps the tcl/tk GUI framework. Did you read and follow the instructions of how to replace the buggy tcl/tk that Apple supplies? Read the entire page before starting! Ignoring this page is the most common reason people have problems with IDLE on the Mac. There are a few others, but I do not remember one that matches your description.
I am using Spyder with Anaconda Launcher.
I was working on some machine learning models and when drawing graphs, I used X_grid = np.arange(min(X), max(X), 0.00000001)
Now the problem is that 0.00000001 takes a LOT of time to execute. Ideally people don't exceed 0.001.
Because of this, there is one process called "python" always showing up in the dock. If I force quit it, the kernel in Spyder dies and restarts and it instantly shows up in the dock again.
The python process icon in the dock looks like this.
I tried googling a lot, checking out answers in stackoverflow but none helped. I also tried completely removing anaconda from my mac, deleting the anaconda folder from the Users folder, then restarting the mac and then reinstalling it. Nothing seems to work! And it is really annoying to see that white icon in the dock.
So can anyone help me get rid of that white python process icon from the dock?
EDIT: I seem to have found the problem. Whenever I try to plot a graph using matplotlib, it used to appear in the console but the process icon used to not appear. To make the graph appear in a separate window, I go to Preferences > IPython Console > Graphics and select Automatic under 'Graphics Backend'. When I do this, this annoying icon appears again! Any help is appreciated.
I just started trying out PyCharm, and while it is very nice, I found the interactive console in debugger (that can be activated with "Show Python Prompt" on a breakpoint) is unusably slow. If I keep pressing enter, for example, after 2-3 tries, I have to wait several seconds for the next prompt to show up.
Is this a common experience? I'm running Pycharm with a pretty fast machine (with i7-3770 CPU) so I was wondering if something is wrong.
I too have experienced the same problem quite a few times but With every new version released new problem too pop out . Its not the first time PyCharm is giving some one a hard time. In previous version the IDE would just stop working or not debug at all .
The best way to solve this is by writing to Jet Brains so they can find and solve the issue and release a new update.
So, recently I was using the Python theme function for the IDLE program itself. I downloaded three themes and built my own one, which is selected now. The problem is, I forgot to set colours for the blinker and highlighting, which is hugely problematic. When I went to see if I could change back to the default setting, Python IDLE simply froze up when I selected 'Configure IDLE' under options. I can still scroll through the file, attempt to close the window and minimise it etc, but it has just frozen up. I can't close it or continue working with the file. I've removed Python and then reinstalled it but that hasn't worked, should I just manually delete the themes and force IDLE to use the original one, or is there a way to fix this?
I am running Python 2.7 on Windows 8.1.
Thanks
Turns out one way is manually deleting the faulty theme. This allows the Configure IDLE menu to open. Whoops.
