I dunno why one would do it without built-in functions, but here’s a working bubble sort example. http://rosettacode.org/wiki/Sorting_algorithms/Bubble_sort#Python def bubble_sort(seq): “””Inefficiently sort the mutable sequence (list) in place. seq MUST BE A MUTABLE SEQUENCE. As with list.sort() and random.shuffle this does NOT return “”” changed = True while changed: changed = False for i in … Read more
This should print the factors for each of the numbers in your list. First we will go through each of the numbers, assume one of these numbers is 4. Then we will go through [1,2,3,4] and find out which of these is a factor of 4. Turns out its [1,2,4]. n = [3,4,5] for i … Read more
The first statement if keyword.lower() in normalized: is checking if keyword.lower() string is one of the elements inside the list normalized. This is True. The other statement if keyword.lower() == normalized: is checking if keyword.lower() string has same value as normalized list. This is False. 1 solved What’s the difference between ‘==’ and ‘in’ in … Read more
You need a little more debugging here. For instance, check that your split gives you what you want. Second, please read https://stackoverflow.com/help/mcve — this lists our expectations for posting. Giving the actual input and error message would have given you an answer much sooner: you fed a list to fnmatch, which expects a string. You’re … Read more
You only defined classes inside the namespace of class User. An instance of User don’t have magically instances of the inner classes (i.e. in Python there is nothing like a inner class). So class definitions inside other classes in normally not useful. You have to give the other classes an explicit reference to your user … Read more

Write response = input(‘Would like to …?’).lower() if response == ‘y’ or response == ‘yes’: … Or if response in [‘y’, ‘yes’]: … Note that it’s not necessary to call str — your object is already a string. solved Test for answers in an IF block [duplicate]
If there is an if statement after an elif, this means this a different block of if statements. For example, if I do yes = “yes” no = “no” if yes == “yes”: print(“yee”) elif no == “no”: print(“:(“) It will only print “yee” as after it stopped after the first one worked. However, if … Read more
You need to check if titletext.a is None before you can use it for sure. for titles in title: titleheading = soup.findAll(‘h2’) for titletext in titleheading: if titletext.a: titlename = titletext.a titlelink =titlename.get(‘href’) print(i) print(titlelink) i+=1 2 solved Non Type object has no attribute get error
Wrap the file name in quotation marks like this “your file.txt” If you have a filepath, use the raw string (and backslashes in the copied filepath) by placing a r before the quotation marks: r”C:\Folder\Subfolder\another_one\your_file.txt” solved how to import .txt with space in filename
This is less easy to find because many of Google’s Cloud (!) services now prefer Cloud Client libraries. However… import google.auth from googleapiclient import discovery credentials, project = google.auth.default() service = discovery.build(“logging”, “v2”, credentials=credentials) Auth: https://pypi.org/project/google-auth/ Now, this uses Google Application Default credentials and I recommend you create a service account, generate a key and … Read more
//This code is for explanation quiz = str(input(“would you like to answer some questions \n choose y/n”)) quiz = quiz.lower() while quiz != ‘y’ and quiz != ‘n’: //here you are using != that will result false this logic works fine with ! //while quiz == ‘y’ or quiz == ‘n’: //will work for or … Read more
The problem is in your original data: >>> [-131.23, 33213, 4454, 566, -33, 465. -377.312, 5.6656] [-131.23, 33213, 4454, 566, -33, 87.68799999999999, 5.6656] because you forgot the comma and this does the substraction: >>> 465. -377.312 87.68799999999999 Just add the comma: >>> sorted([-131.23, 33213, 4454, 566, -33, 465, -377.312, 5.6656]) [-377.312, -131.23, -33, 5.6656, 465, … Read more
If you have the memory to create a set of all tuples from one list then this is the most efficient way. Convert one list to a set of all its tuples and then iterate over the other list. This runs in O(n) time and space complexity. L1 = [8, 80, 53, 70, 90, 24, … Read more
