问题 I have a list containing paths. For example: links=['main', 'main/path1', 'main/path1/path2', 'main/path1/path2/path3/path4', 'main/path1/path2/path3/path5', 'main/path1/path2/path3/path4/path6'] I want to create a nested dictionary to store these paths in order. Expected output: Output = {‘main’: {‘path1’: {‘path2’: {‘path3’: {‘path4’: {‘path6’: {} }},‘path5’:{}}}}} I am new to python coding (v 3.+) and I am unable to solve it. It gets confusing after i reach path 3 as there is path 4 (with

问题 I'm writing a UI wrapper for reading some info using esptool.py I have two active threads: UI and procesing - SerialReader. UI class has reference to the SerialReader and should stop SerialReader when it gets the exit command. The problem is that I call esptool command which gets stuck in trying to read data over serial connection. class SerialReaderProcess(threading.Thread): def __init__(self, window): super().__init__() self.window = window self.logger = window.logger self.window.set_thread

问题 I'm working on a cs50/pset6/dna project. I'm struggling with finding a way to analize a sequence of strings, and gather the maximum number of times a certain sequence of characters repeats consecutively. Here is an example: String: JOKHCNHBVDBVDBVDJHGSBVDBVD Sequence of characters I should look for: BVD Result: My function should be able to return 3 , because in one point the characters BVD repeat three times consecutively, and even though it repeats again two times, I should look for the

问题 From the test.csv file, I have country,first_name,last_name,address Australia,test1,test2,address1 Hongkong,test2,test3,address2 How can I read the csv file and assign country as key in dictionary and test of the row as values? Expected output: {"Australia": ["test1","test2","address1"], "Hongkong": ["test2","test3","address2"]} 回答1: Use a dictionary comprehension txt= '''country,first_name,last_name,address Australia,test1,test2,address1 Hongkong,test2,test3,address2''' {line.split(',')[0] :

问题 In Python 2, it was possible to compare objects of different types such as int to str by having an implicit comparison of the text string of types (that is, in lexicographic order, string 'int' is less than string 'str' and string 'list' is less than string 'tuple' ). Hence, in Python 2, 5 < 'hello' returns True . One can read more about why this was allowed in answer to Why is ''>0 True in Python?. In Python 3, this raises builtins.TypeError: unorderable types: int() < str() exception. This

问题 I have a list of named locations and a set of lat/lng bounds that I want to plug in to the Google Maps API and have it find the locations for me. The names can be very vague, like simply "the boarding school". Using the lat/lng bounds, is there a way I can get GMaps to find these vaguely named locations within the coordinates provided? My application is web-based and powered by Python Flask in the backend. I've tried looking into Maps' Place Search, but it seems like it can only 'prefer' a
