🔒 Beginners Errors

[spare mantle]

I wanted to develop a quiz system (I am a complete beginner), which would check if the entered value is float or anything else. It is not working. Here is the code:-
a = input("Enter a float(nothing else): ")

now, I will store the type of a in another variable, i.e., b

b = type(a)
if(type(a) == float):
print("You answered correctly!")
else:
print("You could not do it correctly!")
print(f"The type of your input is {b}")

Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

the type isn't determined by what is typed into input. input() will ALWAYS be str

remember that digits can still be str

123.456 vs. "123.456"

Is there any way to make such a code as I had said before?

[gleaming snow]

you could just do this (if you know except)

a = input("Enter a float: ")

try:
    a = float(a)
    print("Good!")
except ValueError:
    print("No!")

[delicate fog]

Yes exactly, if you want to verify that what the user enters works as a valid float, it's common to just use try/except

we basically attempt to convert to float and see if that would have caused an error

[spare mantle]

Okay. Thanks for the quick help!

[gleaming snow]

can't really think of another way to check for float without except 🤷‍♂️
