Write a program to prompt for a score between 0.0 and 1.0. If the score is out of range, print an error. If the score is between 0.0 and 1.0, print a grade using the following table: Score Grade >= 0.9 print A, Grade >= 0.8 print B, Grade >= 0.7 print C, Grade>= 0.6 print D, Grade < 0.6 print F If the user enters a value out of range, print a su…

3.3.py

score = float(raw_input("Enter score between 0.0 and 1.0: "))
if score>1.0 or score<0.0 :
	print "error"
elif score>=0.9 :
  	print 'A'
elif score>=0.8 :
    print 'B'
elif score>=0.7 :
    print 'C'
elif score>=0.6 :
    print 'D'
else :
    print 'F' 

what if input is a string

Your program does not have any output

what if input is a string

you will get an error stating that "couldn't convert string to float"

there is an error in line 2,we should not use and operator
it is suppose to be like -->if score>=1.0 or score<0.0

#This works

score=input('Enter score: ')
try:
sc=float(score)
except:
print('Sorry, try a number.')
quit()
if float(score) > 1.0 or float(score) < 0.0 :
print('Sorry, not in range')
elif float(score) >= 0.9 :
print('A')
elif float(score) >= 0.8 :
print('B')
elif float(score) >= 0.7 :
print('C')
elif float(score) >= 0.6 :
print('D')
else :
print('F')

sc = (input('enter the score: '))

def grades():
if score >=0.0 and score <=10.0 :
if score >=0.9:
print("a")
elif score>=0.8:
print('b')
elif score>=0.7:
print('c')
else:
print('fail')
else:
print("out of range")
try:
score=float(sc)
except:
print('bad score')
quit()
grades()

score= input('Enter score : ')
try:
scr= float(score)
except:
print("Enter a valid number and try again")
quit()

if scr <= 1.0:

if scr >= 0.9:
        print('A')
elif scr >= 0.8:
        print('B')
elif scr >= 0.7:
        print('C')

elif scr >= 0.6:
        print('D')

elif scr <0.6:
        print('F')

else:
print('Input out of range ,Please correct it')

this works perfectly.
make sure you give some space before writing print(don't make indentation error).

score=input("Please type a score between 0.0 and 1.0:")

float(score)
if float(score) >1.0 and float(score) < 0mmm.0:
print("error")

print("A")

print("B")
elif float(score) >= 0.7 and float(score) <= 0.8:
print("C")
elif float(score) >= 0.6 and float(score) <= 0.7:
print("D")
elif float(score) > 0 and float(score) <= 0.6:
print("F")
else:
print("enter valid score.")
except:
print("enter valid score.")

score = float(input("Enter score between 0.0 and 1.0: "))
if score>1.0 or score<0.0 :
print ("error")
elif score>=0.9 :
print ('A')
elif score>=0.8 :
print ('B')
elif score>=0.7 :
print ('C')
elif score>=0.6 :
print ('D')
else :
print ('F')

score= input('Enter score : ')
try:
scr= float(score)
except:
print("Enter a valid number and try again")
quit()

if scr <= 1.0:

if scr >= 0.9:
        print('A')
elif scr >= 0.8:
        print('B')
elif scr >= 0.7:
        print('C')

elif scr >= 0.6:
        print('D')

elif scr <0.6:
        print('F')

else:
print('Input out of range ,Please correct it')

This says bad input on line 3

Improve your grogram in Question 1 by adding try and except. If a non-numeric input is
submitted, your program should print a message and exit the program.
Example input and output:
Enter Hours: 50
Enter Rate: ten
Error, please enter a numeric dat
