Final answer:
The code fragment has an issue with the comparison operator used. It should use '==' instead of '='.
Step-by-step explanation:
The code fragment has an issue in the line 'If color = 'purple':'.
The issue is that a single equal sign (=) is used for assignment, not for comparison. To compare two values, the '==' operator should be used. So the correct code should be: 'If color == 'purple':'.
By using the '==' operator, the code will check if the value of the variable 'color' is equal to the string 'purple'. If the condition is true, it will print 'Cool!'. Otherwise, it will not print anything.
