# Python Code Challenges: Control Flow (Advanced) Number 5

Create a function called `max_num()` that has three parameters named `num1` , `num2` , and `num3` .

The function should return the largest of these three numbers. If any of two numbers tie as the largest, you should return `"It's a tie!"` .

# Write your max_num function here:

def max_num(num1, num2, num3):
if(num1 > num2 and num1 > num3):
return str(num1)
elif(num2 > num1 and num2 > num3):
return str(num2)
elif(num3 > num1 and num3 > num2):
return str(num3)
elif(num1 == num2 or num1 == num3 or num2 == num3):
return “It’s a tie!”

# Uncomment these function calls to test your max_num function:

print(max_num(-10, 0, 10))

# should print 10

print(max_num(-10, 5, -30))

# should print 5

print(max_num(-5, -10, -10))

# should print -5

print(max_num(2, 3, 3))

# should print “It’s a tie!”

print(max_num(5, 2, 0))

When I click ‘Check Answer’, it gives me "max_num(5, 2, 0) should have returned 5, and it returned 5. I’m not sure if it is flagging my response as wrong because my logic is wrong somewhere in my code, or if it is just incorrect. When I run my code the last line prints in the counsel as 5.
