Shouldn’t the a* match with the a in the string? No, because * means a can match zero or more times, so the ” empty string also matches that expression. That leaves ‘ad’ after the initial empty string to match for the remainder of the expression. A regex will consider both options here (both ”, … Read more

Based on the description you gave, the desired output appears to be: the count (0..10000) of each number from one to six; and the average of all numbers. So you’ll probably want something like this: Number 1 occurred 1662 times. Number 2 occurred 1676 times. Number 3 occurred 1600 times. Number 4 occurred 1696 times. … Read more
You can try this (it’s version of Python3): n = int(input()) arr = list(map(int, input().rstrip().split())) result = 1 for num in arr: result = (result * num) % 100 print(“{:02d}”.format(result)) A little bit modify for better algorithm: n = int(input()) arr = list(map(int, input().rstrip().split())) result = 1 for num in arr: result = (result * … Read more

I have made a replica of your case but in my case the custom error handler works. I created this example since cloud shell editor. I share with you my code I hope are helpful for you: app.py: “”” A sample Hello World server. “”” import os import requests from flask_limiter import Limiter from flask_limiter.util … Read more
You could just check the input with if else and raise an Error if needed with a custom message if original_input == “”: raise RuntimeError(“Empty input”) else: # Your code goes there As a side not, input() is enough, no need to add quotes “” Edit: This question was edited, the original question was to … Read more
As was mentioned by cco: if data.char in “123456789” data.board[row][col] = int(data.char) The in operator evaluates to true if it finds a variable in the specified sequence and false otherwise. It can be used for lists, strings, tuples and dictionaries. However the in will only check the keys of the dictionary – not the values. … Read more
If you want to extend your solution to make sure the leading digit isn’t 0, there’s probably no super-concise way to write it; just be explicit: first = random.choice(range(1, 10)) leftover = set(range(10)) – {first} rest = random.sample(leftover, 3) digits = [first] + rest Notice that I’m taking advantage of the fact that sample takes … Read more
Well, lets make your code a little more pythonic… import random DECK_SIZE = 5 # See that it generates 5 unique random number from 1 to 12 # (not including 13) thus simulating a deck of cards, # where cards cannot repeat. We add a None in the end to # indicate end of deck … Read more

You use dot for 3 main reasons: Accessing members of a module: a module is simply a python file, and members can be variables, functions, classes and so on. Accessing modules within a package: a package is a directory containing a__init__ module. Some packages are nested and contain inner packages. You have to reach the … Read more

Well try to debug your code by yourself first. Anyhow for your question Why is this happening? : It gives you error in postCode = split_address[4] because your list has 4 elements 0,1,2,3 and you are accessing the 4th element which is not present.. you don’t have the index[4] thats why it gives you error … Read more
This is very simple, and is pretty much related to your understanding of the BMI’s formula. The code that suits your requirements would be the following: maxweight = (height**2/10000)*24.9 dif = round(abs(maxweight-weight),2) print(name+”, you have”,dif,”kilograms to go until you reach the maximum normal weight”) This works for both underweight and overweight values, always returning a … Read more
