— In the first one, a is '5', it can be converted to int
in the second one, a is '5.5', it can't be converted to int, you have to cast it to float first

You can think of it like this
when a = 5.5
You cannot simply say
B = int(a)
Because that would be like saying
B = int(5.5)
And int cannot take a float value thus this will throw you an error

— Look at it rookie you can cast to float in both cases

— Have you noticed the difference?

— So 5.5 a not incorrect form? a float 5.5 can and a str 5.5 cant. is there any chance the python can tell the dot "."from str? maybe python sentenced the dot to be and only can be a full stop?
