Can we put float or non-integral values while inputting it from user side and convert the final output of the two no.s??

Question

I am suggesting like this if anyone can help me because it states that if non-integral value or float passed as an input it can cause error.
Below is the example which I did work upon it executed without any error:
>>>float(input("Enter a:")) + float(input("Enter b:"))
Enter a: 40.0
Enter b:3.5
43.5
Please can anyone clear my doubt???

Answer 1

float(input()) tries to convert your input, which is of string format, to float.

If you write '40.0', that works, because Python can understand it as a float.

But if you write '40.z', you will get an error, because that string doesn't make sense as a float.

Answer 2

Hey HonFu [#GoGetThatBugChamp!] Actually asked about numbers so there z can't be put and I also put 3.5 as an input value so python considers float but in that lesson they mentioned that we can't take float or non-integral values as it can cause error so then can you explain it once again??

Answer 3

I just looked it up.

I think it is sloppily written. They seem to mean this:

non-(integer or float)

Answer 4

But, then which numerical values can't be considered and cause an error??

Answer 5

They just mean, that the string has to come in a shape that is recognizable as an int or a float, and not something like 'shulrtzg'.

Answer 6

Okay as per your answer it is clear that all numerical values are accepted except string values
Thanks
