Python 24K Magic

Question

Hi, I am new to coding...

I don't understand how I get Python to not output anything if the value is lower than 75%.

Here's my code:

purity = float(input())
if (purity >= 99.9):
print ("24K")
elif (purity <= 91.70 and purity >= 99.8):
print ("22K")
elif (purity >= 83.3 and purity <= 91.6):
print ("20K")
elif (purity >= 75.0 and purity <= 83.2):
print ("18K")

Can someone help?

It fails two of the 7 test cases... I suspect with numbers below 75.0

Answer 1

purity = float(input())
if purity >= 99.9 :
print ("24K")
elif purity >= 91.7 :
print ("22K")
elif purity >= 83.3 :
print ("20K")
elif purity >= 75 :
print ("18K")
else:
print ("?K", purity) # Unknown

It would not hurt to find out the assignment.

Answer 3

Take another look at your condition for 22K. It's impossible to fulfill it.
Also, notice that there are gaps between your categories.
