Noticing major flaws on this site.

Question

i keep noticing the wording of problems has been REwritten to not match the answers to the code challenges.

This is a HUGE issue as to no one will pass the certifications unless they look up old answers.

Look at the purities being asked for in the question. If you write the code in reference to those it will be concluded as INCORRECT.

I had to look up someones old answer with purities NOT matching the question to pass the code challenge --->
PASSING CODE BELOW:

purity = float(input())
#your code goes here
if purity >= 99.9:
print("24K")
elif purity >= 91.7 and purity < 99.9:
print("22K")
elif purity >= 87.5 and purity < 91.7:
print("21K")
elif purity >= 83.3 and purity < 87.5:
print("20K")
elif purity >= 75.0 and purity < 83.3:
print("18K")

Answer 1

you mean Python for beginner: practice 24.2? looks good to me.

And you don't need those ANDs, the second condition is already obviously true if the execution gets to that point.

REAL PROOFS: --->

This says in the question:
"Here is the purity chart we’ll be using:
24K – 99.9%
22K – 91.7%
20K – 83.3%
18K – 75.0%"

Same as in your code, and you don't need the 21K
