Python code not running, do I need to reinstall python?

Question

So when I'm trying to run this code. As you can see it asks for a number as an input.

print('How old is Vini?')
number= 17
guess= int(input('enter a number'))
if guess== number:
    print('Bravo Vini is 17')
elif guess < number:
    print('Vini is older than '+guess)
elif guess > number:
    print('Vini younger than '+guess)

Now if the number is equal to 17 it executes but if the number is higher or lower it gives me this error:

When the number is higher:

Traceback (most recent call last):
  File "C:\Users\ervin\Desktop\loja.py", line 9, in <module>
    print('Vini younger than '+guess)
TypeError: must be str, not int

When the number is lower:

Traceback (most recent call last):
  File "C:\Users\ervin\Desktop\loja.py", line 7, in <module>
    print('Vini is older than '+guess)
TypeError: must be str, not int

don't mind the title ( do I need to reinstall python? ), I just needed the website to accept the question. — Erson Cokaj, Jan 09 '18 at 20:12
Why would your first consideration be to reinstall python rather than investigating the error message? — roganjosh, Jan 09 '18 at 20:12
`print('Vini is older than '+guess)`=>`print('Vini is older than '+str(guess))` (dirty, but works) — Jean-François Fabre, Jan 09 '18 at 20:13
See above.. and fix the title to avoid an excessive number of reactionary downvotes. Because the answer is: ***No**, you should fix your code*. — user2864740, Jan 09 '18 at 20:13
I'd be more inclined to `print('Vini is older than', guess)` than use conversion and concatenation. — Fred Larson, Jan 09 '18 at 20:14
also, reboot your computer, just in case this will fix it: https://www.youtube.com/results?search_query=it+crowd+have+you+tried+turning+it+off+and+on+again — Jean-François Fabre, Jan 09 '18 at 20:14
you don't need to reinstall python, you need to _rewrite_ python so you can add strings with integers like in Javaaaaah — Jean-François Fabre, Jan 09 '18 at 20:15
@Mangohero1: I don't believe that applies. The title is poor, but the question meets everything mentioned in the "itsnotworking" link. — Fred Larson, Jan 09 '18 at 20:24
@Mangohero1 Chill out dude. I mean, I can clearly see that you cannot wait until someone who's new posts a question and you can jump in to post that but... come on, show some maturity :) — Erson Cokaj, Jan 09 '18 at 20:36
Weeellll I guess that was a little insensitive. But! I didn't quite post it like that! — Mangohero1, Jan 09 '18 at 20:55
no worries, anyway my problem was solved :P so thanks to all of you for taking your time :) — Erson Cokaj, Jan 12 '18 at 12:22

You need to convert guess to a string for the print statements to work, try writing + str(guess) instead of + guess.

Your method works. But what if I want the guess to be an integer? – Erson Cokaj Jan 09 '18 at 20:21
@ErsonCokaj `str(guess)` doesn't permanently change `guess` into an string, it's only used as a string for that occurence, in this case in the `print`, it won't have any side effects – Nick is tired Jan 09 '18 at 20:23
@NickA ok thanks, very helpful :) – Erson Cokaj Jan 09 '18 at 20:32

In statement print('Vini is older than '+guess) you are trying to concatenate a string('Vini is older than ') with an integer(17) which is wrong hence the error that you are getting.

Use

 print('Vini is older than '+str(guess))

str(guess) converts the integer to a string. Now you are concatenating two strings which is valid.
