If i understand the problem correctly it should take first int then scan the n lines and creating sort of 2 dimension list/array or so then should accept int of questions about what is in position (x,y) in this 2 dimensional object covering what is out of bounds as an “ERROR!”. import java.util.ArrayList; import java.util.Scanner; … Read more
Introduction If you are getting an erroneous output when running a program, it can be a frustrating experience. It can be difficult to determine the cause of the problem and even more difficult to find a solution. This article will provide an overview of the most common causes of erroneous output and provide tips on … Read more
From what I can tell, it seems like you want to create a list of a bunch of random features. The way I would personally go about this is by using the random method Choice Choice allows us to pick a string from a list, then we use a function called .append that lets us … Read more
If I understand correctly, you want to find the first positive integer number that is not in the list. (since you’re using “the” first number, I assume you don’t need an array of numbers with all holes.) The way you do this is (assuming the array is sorted like in your examples) is by simply … Read more
Hoo boy, this was a big XY problem. You want to sort by the third character of the second element of each tuple. Use the sorted built-in with its kwarg key. lst = [(‘abc’, ‘bcd’), (‘abc’, ‘zza’)] result = sorted(lst, key=lambda t: t[1][2]) key here accepts a function that is given each element in turn, … Read more
myList = [] while True: word = input(“Enter a Word (Type ‘q’ to quit): “) if word == ‘q’: break myList.append(word) print(myList) RESULT Enter a Word (Type ‘q’ to quit): cat Enter a Word (Type ‘q’ to quit): dog Enter a Word (Type ‘q’ to quit): rat Enter a Word (Type ‘q’ to quit): q … Read more
Use a list comprehension in combination with join method. result=” “.join([”.join(item) for item in my_list]) Output ‘hiiuih rm hgizgvtb xzmmlg yv xliivxg gsilfts gzxgrxzo nzmvfevih’ solved Python – Create string from list of list of characters [closed]
Here is a basic example. rainbow = [‘Program Ended’, ‘Red’, ‘Orange’, ‘Yellow’, ‘Green’, ‘Blue’, ‘Indigo’] user_input = int(input(“Please select a number between 1 and 6: “)) if user_input > 0 and user_input < 7: print(rainbow[user_input]) else: print(“Program ended”) To capture a user’s input, you simply invoke: input() function. To access an array, you can do … Read more
Try this var OuterBrackets_List= lst.Where(s => s.StartsWith(“[“) && s.EndsWith(“]”); var AlphaNumeric_List = lst.Except(OuterBrackets_List); 1 solved how to extract those elements from the list which have square bracket in c# [closed]
The first declaration creates a list with an underlying array with a size of 5. The second declaration copies data from the passed array to the underlying array in the list. So the second declaration needs to: Create an empty array Copy the values in that array to another array Since it’s also harder to … Read more
since you just want code it sounds like from operator import itemgetter sorted(map(itemgetter(1,-1),lists),key=itemgetter(-1)) heres some code that should do what you want … a teacher may want an explanation however… just fair warning solved Python: Sorting and printing lists within lists [closed]
Use the Counter. from collections import Counter A = [[1,2], [2,1], [3,1], [1,2]] print Counter(tuple(i) for i in A) >>> Counter({(1, 2): 2, (3, 1): 1, (2, 1): 1}) 1 solved Getting a count of list elements [closed]
There are many possible solutions. In my opininion this is the easiest: import heapq list1 = [2,5,7] list2=[4,6,9] counter1=0 counter2=0 sum1=0 sum2=0 full_list = list1 + list2 three_largest = heapq.nlargest(3,full_list) for n in three_largest: if n in list1: list1.remove(n) counter1+=1 sum1+=n else: list2.remove(n) counter2+=1 sum2+=n print(counter1) print(counter2) print(sum1) print(sum2) Note that you made a mistake … Read more
Assuming I understood your question, these should do it: for person in sorted(cat1): print(person, max(cat1.get(person))) result: ben 9 jeff 6 sam 9 then: for person in sorted(cat1, key=lambda x: max(cat1.get(x)), reverse=True): print(person, max(cat1.get(person))) result: ben 9 sam 9 jeff 6 then: for person in sorted(cat1, key=lambda x: sum(cat1.get(x))/len(cat1.get(x)), reverse=True): print(person, sum(cat1.get(person))/len(cat1.get(person))) result: ben 7.666666666666667 sam … Read more
I think this is what you need.I have commented the code for your understanding import java.util.ArrayList; import java.util.List; public class demo { public static void main(String[]args){ List<Integer>list1=new ArrayList<Integer>(); List<Integer>list2=new ArrayList<Integer>(); List<Integer>list3=new ArrayList<Integer>(); ////here add your values to the list,i have not added them.You first need to add the values to the list //then iterate through … Read more
