I am writing a script to add missing keys within a list of dictionaries and assign them a default value. I start by building a set of all the possible keys that appear in one or more dictionaries. I adapted a nice snippet of code for this but I’m having trouble fully wrapping my head ..
I already know about *(iterable unpacking) and **(dictionary unpacking) for unpacking and also pass as an parameter for a function or method. But in many cases I see someone using * without any name like this example below: def simple_func(arg1=None, *, data=None, …): … What this meaning? Thanks in advance! Source: Python-3x..
I am currently working on building a piece of code that is composing business objects from tuples that it has been given by the data source I am using. Since these tuples may vary in length and their naming, I want to insert a pre-defined tuple into the for loop. class_attributes = ("_id", "_first_name", "_last_name") ..
I am solving the coin change problem. I run code on jupyter-notebook with the given example on leetcode and it works. The same code does not work on leetcode. causing syntax error: Here is the code to copy: def best_sum(target,nums): dp=[None for y in range(target+1)] dp= for i in range(len(dp)): if dp[i]!=None: for num in ..
lst = [‘first’, ‘second’] for q,w in lst: print(q) print(w) If I set my code like this, the result is an error. But if I do this way: lst = [[‘first’, ‘second’]] for q,w in lst: print(q) print(w) The output is #first #second . I don’t understand the mechanism for this.. can somebody help me? ..
I have filtered a group of students into three buckets using a for loop and by unpacking a tuple. How can I attach their corresponding student numbers to each score? Thank you. #create index for 100 students, starting with 1 student_index = list(range(1,101)) #join index with results sheet student_score_index = list(zip(student_index, results_sheet2)) group_a =  ..

I don’t yet understand why this python code doesn’t work; it’s part of a little game we are making. The following function is part of a class: def detectCollision(self,other): if(self.x < other.x + other.w and self.x + self.w > other.x and self.y < other.y + other.h and self.y + self.h > other.y): return (self,True) Later ..
