Problems with Python code

Hello, guys! I probably shouldn't mentioned it, because in other forums no one really wanted to help me after I mentioned that I need this for my programming test at school, but I'm really desperate. I will attach my code and errors in it, I don't really understand what is wrong with these errors and how can I fix them. I am already trying to write that program for 3 days. But if I can't get pass this test, it looks like there is almost 100 percent chance for me not to make to next grade. And also don't misunderstood me- I don't want to get into job as a programmer, but I have that subject at school. And if someone really helps me, please explain as simple as you can, because I really don't understand what these errors mean. Really hope on your help, because I'm myself hopeless with this. Thank you :)))




x = int(input())
a = 12
sestdiena = x//a

print(sestdiena , str(sestdienaa) + "/" + str(a))
