How can I concatenate str and int objects

Question

How To Concetanate Strings and Integers in Python?
I am trying to execute the following code:
things = 5
print("You have " + things + " things.")
I get the following error in Python 3.x:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: must be str, not int

Answer 1

'+' operator can be used to either add two numeric values or to concatenate sequences.
For example:
A = 1
B = 2
Print (A + B)
Output = 3

Print ([1,2,3,’name’] + [1,2,5, ’name’])
Print (‘string-1’ + ‘string-2’)
Output = [1,2,3,’name’,1,2,5,’name’]
Output = string-1string-2

Answer 2

>>> [1, 2, 3] + [4, 5, 6]
[1, 2, 3, 4, 5, 6]
>>> 'abc' + 'def'
'abcdef'

Answer 3

1. either: print("You have " + str(things) + " things.") (the old school way)

2. or: print("You have {} things.".format(things)) (the new pythonic and recommended way)

Answer 4

If you want to concatenate int or floats to a string you must use this:

i = 123
a = "foobar"
s = a + str(i)
