Coursera issue for me

Solution 1:

You have to define fraction1 in your code.

You are only creating fraction1 variable inside the while loop and that while loop only runs when fraction > 1.

What if fraction <= 1? You don't have any variable called fraction1 created anywhere in your code.

And at the end your function returns fraction1 which isn't defined.

Also you must decrease fraction by 1 inside the loop else the loop goes on indefinitely.

def fractional_part(numerator, denominator):
# Operate with numerator and denominator to 
# keep just the fractional part of the quotient
   if denominator == 0 or numerator == 0:
       return 0
   else:
       fraction = numerator / denominator
       fraction1 = 0
       while fraction > 1:
           fraction1 = fraction - 1
           fraction -= 1
       return fraction1
        

Solution 2:

to solve this you will need to remove the Floor division so we use this Python Arithmetic Operator //

def fractional_part(numerator, denominator):
      if denominator == 0 or numerator == 0:
         return 0

      else:
          fraction = ((numerator / denominator)-(numerator // denominator))
          return fraction
    

print(fractional_part(5, 5)) # Should be 0
print(fractional_part(5, 4)) # Should be 0.25
print(fractional_part(5, 3)) # Should be 0.66...
print(fractional_part(5, 2)) # Should be 0.5
print(fractional_part(5, 0)) # Should be 0
print(fractional_part(0, 5)) # Should be 0

Output
