[Tutor] A question about daunting KeyError
Hi tutors on Tutor, I'm Taishi from Japan working in a data analytics team. Currently, I'm trying to analyse purchase data of a fashion brand. However, mysterious KeyErrors started occurring continuously when I was coding, and I haven't been able to get that fixed. Although I asked this question on Stack Over Flow and another platform, I haven't got any solution. I'm suspecting that Anaconda might keep raising the error, or simply there are bugs in the codes. However, I can't be sure what the real cause is. Do you think you can help me out? If yes, please give me some assistance. Regards, Taishi Kawamura ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

People here are happy to help, but you'll need to show us the relevant code and perhaps some data if that's possibly the source of the problem. -- Regards =dn ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Start by removing Anaconda from the problem: what happens if you run your code using the plain Python interpreter, without Anaconda involved? >From the operating system command line, run something like this: # Windows CMD.EXE py path/to/myscript.py # Linux or Mac OS shell python path/to/myscript.py Of course the example command you run will depend on the version of Python you are using, and the name and path to your script. If the error goes away without Anaconda involved, then it is *possible* that it is a bug in Anaconda. But I expect the error will remain. Then show us the full traceback of the error. Copy and paste the FULL exception message, starting with the line "Traceback" and ending with the KeyError and error message, something like this but probably longer: Traceback (most recent call last): File "", line 1, in KeyError: (1, 2, 3) Once you know the line where the error is occurring, you could introduce some debugging code: try: result = data[key] except KeyError: log(data) log(key) raise or use the debugger to investigate why the key is missing. You should also read this: http://sscce.org/ It is written for Java programmers, but it applies to Python too. -- Steven ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] python idle file couldn't start
What (precisely) did you type to "start python through idle"? Don't guess - cut and pasted EXACTLY what you type and what you see on screen.

[Tutor] __weakref__ question
Can anyone provide some simple example/s or two or three of using weakref? I'm baffled and not seeing any documentation that is meaningful. My interest is to minimize memory usage (generally speaking, overall) and am wondering if this might help. --- We not only inherit the Earth from our Ancestors, we borrow it from our Children.
