what do I do to get a int and a str to concatenate?
I am playing with the idle but I can't seem to make this work.

name = input('enter your name: ')
age = int(input('enter your age: ')) 



while ( name != " " ):
    print('hello ' + name + ' you are ' + age + " years old")
    if (age < 18):
        print('go home kid')
    elif (age > 100):
        print('really hanging in there huh')
    break

I also tried age=input('enter your name') to no avail.


print('hello' + name + 'you are ' + int(age) + ' years old' didn't get it either.


I'm just messing around and wondering why is it that I am having a hard time trying to print
hello str you are int years old? with the conditions in the code also.

Please use proper code tags while posting a thread.
The problem is python can't just join a string and an integer together, because they are two different things and hence Python has no clue - should it add them like an integer or join them like a string ??
So there are 2 ways to defeat this -

1. First, you can change the integer into a string, like
   

   print('hello ' + name + ' you are ' + str(age) + " years old")

   OR
   
   
2. You can use commas -
   

   print('hello ' , name , ' you are ' , age , " years old")

Python doesn't know how to add a word and a number, so it says "cannot concatenate 'str' and 'int' objects." A word that you put in quotes is just a string of letters called a str in python. Numbers that don't have a decimal point are integers and are called int in python.

Or you can use f string format

age = 20
print(f'Hello, I am {age} years old.')

I had totally forgotten about f-strings

thanks for the replies, the thing is I didnt realize that I was adding.
so the commas was the way to go for this instance, thanks again.
btw I am not 100 percent sure what is meant by placing tags but I will look into that.
