When manipulating structures such as URLs it’s better to use tools designed for the purpose rather than treating them as strings. In this case you want to change the host (netloc) to www.site2.com So… from urllib.parse import urlparse, urlunparse new_site=”www.site2.com” url=”https://www.site1.com//vehicles/2023/Ford/F-150/Calgary/AB/57506598/?sale_class=New” scheme, _, path, params, query, fragment = urlparse(url) new_url = urlunparse((scheme, new_site, path.replace(‘//’, “https://stackoverflow.com/”), … Read more

One way to do it using sum(), list comprehension and recursion, def simulated_sum(input): “””This is a recursive function to find the simulated sum of an integer””” if len(str(input)) == 1: return input else: input_digits = [int(x) for x in str(input)] latest_sum = sum(input_digits) return simulated_sum(latest_sum) input = int(input(‘Enter a number’)) print(simulated_sum(input)) DEMO: https://rextester.com/WCBXIL71483 solved How … Read more

To set a default value in a function you should do like in the code bellow and you don’t have to use str to convert x to a string, just send the string. def multiply(x,mult_int=10): return x*mult_int print(multiply(“I hope that’s not your homework.\n”, 2)) print(multiply(“Bye.”)) 1 solved The function should return the string multiplied by … Read more

you can try in this way a=input(‘input:’) while a.strip()!=”: b=a.split() ans=”” while len(b) >0 : word=b[0][::-1] ans+=word+” ” b.pop(0) print ans a=input(‘input:’) #output i ma hsejar !aloH 0 solved How can i use a while loop on this program?

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
