what is happenning in the below code

Question

code vizulation is not giving any better answer,here where is the input given and i understood back processes but i couldn't understand how the input is giving.Hope for the best and fast reply
Thanking you all
class Solution(object):
def mergeAlternately(self, word1, word2):
m = len(word1)
n = len(word2)
i = 0
j = 0
result = []

while i < m or j < n:
if i < m:
result += word1[i]
i += 1
if j < n:
result += word2[j]
j += 1

return "".join(result)

Answer 1

CHENNAMSETTY SUMANTH ,

to use the code as it is, we can give input values like this:

sol = Solution() # create an instance of the class `Solution`
print(sol.mergeAlternately('abc', 'xyz')) # now we can call the method `mergeAlternately()` and pass 2 strings to it. str1: `abc`, str2: `xyz`.
# since the method returns the merged string, print will output it. => `axbycz`.

Answer 2

CHENNAMSETTY SUMANTH ,

the code is oop, so we create a class first. this is like a blueprint to create an instance of the class where we are working with.

btw: we don't need `object` as argument, this was required in python 2, but for python 3 it is not.

Answer 3

What is the purpose of the first line that
class Solution(Object):

Answer 4

Normally we do like class Solution:
That's it what is (object) means.
It is just I'm asking because on leetcode the inputs are taken without any other code than i mentioned above
Thanking you

Answer 5

CHENNAMSETTY SUMANTH ,

class Solution(object):

That first line says that the class you are creating inherits from the class called object.

object (not Object) is the built-in base class for all other classes.

I think that it was best practice in Python 2 to always explicitly (manually and visibly) inherit from object, but it is not needed in Python 3 because Python 3 made the behavior implicit (automatic and invisible), or something.

https://docs.python.org/3/library/functions.html#object

In my opinion, naming a class "object" was a horrible design choice, because it clashes with the existing industry term "object" that already means "instance of a class". It also makes it nearly impossible to find the search results you want, because the industry term is so much more common.
