num1=10 num2 = 20 num3="30" sum = num1+num2+num3 print (num1) print (num2) print (num3) print (sum)

The error is at line 3. The variable num3 has been assigned a string value with use of the quotes.

To fix the error, take away the quotes from the number 30, since the arithemetic operation cannot be carried out on the string in python program language.
