keyerror

问题 I’m writing a program that pulls a list of departments from a database. I want to avoid hardcoding this since the list may change. I want to create a variable for each department to populate questions into a GUI. The problem I have is that I can create variables from the database list using the vars() function. I’m then storing the list of variable names so I can reference them elsewhere in my program. As long as I do everything in the same def, there is no problem. But I don’t know how to

问题 When I try to click on data frames in the Variable Explorer in Spyder, I get the following error: This happens with all data frames (I tried making my own). As a side note, functions like numpy.sum and .describe() don't output anything, but I'm unsure if this is related to the KeyError.

问题 I'm facing a KeyError I can't explain or understand. I have a notebook, in which I define a variable PREFIX in a cell: PREFIX = "/home/mavax/Documents/info/notebook/log_study" which is simply a path to a folder containing logs, so people using the notebook just need to change the path if they want to execute the code below. Then, later (quite a bunch of cells beneath), I use it, without any problem: for basename in ["log_converted_full.txt", "log_converted_trimmed.txt"]: entries = load_log

问题 This question already has answers here : Why dict.get(key) instead of dict[key]? (10 answers) Closed 4 years ago . Why does this throw a KeyError: d = dict() d['xyz'] But this does not? d = dict() d.get('xyz') I'm also curious if descriptors play a role here. 回答1: This is simply how the get() method is defined. From the Python docs: Return the value for key if key is in the dictionary, else default. If default is not given, it defaults to None, so that this method never raises a KeyError. The
