I keep getting errors and I'm lost!

After doing step 2 my code is not producing anything :( idk what I'm doing wrong.

def computegrade(score):
    
  while True:
# if letters are entered instead of numbers, 
#program will send "Bad Score" to user and 
# ask user to "Enter score or type 'Quit' to exit".
    try:
      score = float(input("Enter score or type 'Quit' to exit: "))
    except:
      print("Bad score.")
# if "Quit" is entered by user, 
# "Thanks for using the grade calculation program!" will print and 
# end the program.  
      if float(score) == "Quit":
        print("Thanks for using the grade calculation program!")
        quit()     
        continue

 
# if a number is entered that is larger than 1.0, program will 
# send "Bad Score" to user and ask the user "Enter score or type 
# 'Quit' to end program".    
      if float(score) > 1.0:
        print("Bad score.")
       
       
# if number entered is equal to 1.0 or in between 1.0 and 0.9 it 
# will print "A"
      elif float(score) == 1.0 or float(score) >= 0.9:
        grade = ("A")
        print("A")
       
 
# if number entered is equal to 0.89 or in between 0.89 and 0.8 it 
# will print "B"
      elif float(score) == 0.89 or float(score) >= 0.8:
        grade = ("B")
        print("B")
       
 
# if number entered is equal to 0.79 or in between 0.79 and 0.7 it 
# will print "C"
      elif float(score) == 0.79 or float(score) >= 0.7 :
        grade = ("C")
        print("C")
       
   
# if number entered is equal to 0.69 or in between 0.69 and 0.6 it
# will print "D"
      elif float(score) == 0.69 or float(score) >= 0.6:
        grade = ("D")
        print("D")
       
 
# if number entered is less than 0.6 it will print "F"
      elif float(score) < 0.6:
        grade = ("F")
        print("F")
    return grade
    print(computegrade(score))
