Why the given code worked?

I learnt that two different types can't be added but in the given case it worked. https://code.sololearn.com/cJ51odcOXsdm/?ref=app

You can't add objects like strings and numbers (int, float). Adding numbers of different types is no problem (as you can see). The result of any mathematical operation including an int and a float will always be a float: print(5+5.0) # result: 10.0 int+float=float

Python automatically converts integers to floating point numbers, when used in the same operator.

Ashutosh Dash Because you can't add numbers and strings. str("4") takes "4", which already is a string because of the quotation marks, and "converts" it to a string. The result will be a string and you'll end up with the attempt to add a float and a string. float(3) + int("4") on the other hand will work.

Python interpreter implicitly convert your int into a float, because you try adding an integer and a float.

Float and int are numbers, while string are completely different types : characters.

So number + number = OK But number + character = ERROR
