IndentationError: unexpected indent

Question

It keeps saying there is an unexpected indentation. Even after i delete it. What could be the issue?

purity = float(input())
#your code goes here
purity = 93.4;
if purity < 91.7:
print ("Not accepted")
if purity > 91.7:
print ("Accepted")
if purity > 99.9:
print ("Accepted")

Answer 1

purity = float(input())
#your code goes here
purity = 93.4;
if purity < 91.7:
print ("Not accepted")
if purity > 91.7:
print ("Accepted")
if purity > 99.9:
print ("Accepted")

#Try this

Answer 2

You mostly indent the line after a line that ends with a colon (:).
