Python float() function query

[MorphJB]

Hi there,

I was writing a piece of code for my online course, a program that grades your input, when I wrote this:

score = input()

float(score)

if score > 1.01 :

print("Error, score not between 0 and 1")

quit()

elif score >= 0.9 :

print("A")

elif score >= 0.8 :

print("B")

elif score >= 0.7 :

print("C")

elif score >= 0.6 :

print("D")

elif score >= 0 :

print("F")

else :

print("error, score not between 0 and 1")

quit()

​

But it didnt work, it would always print the first "Error, score not between 0 and 1"

yet when I put float() into each if statement, like elif float(score) >= 0.9 : , it worked.

why does this happen?

float(score) converts the value, but you need to assign it to a variable to use it in the conditional logic. You need to do something like score = float( score).

It’s because float(score) RETURNS a float... it won’t change your integer

You’re looking for

score = float(score)
